Bring your own IP addresses (BYOIP) in Amazon EC2

Posted on by admin

At INTERLIR Marketplace, you have the option to rent IP addresses that can be utilized as Amazon EC2 BYOIP (Bring Your Own IP) addresses. This allows you to bring a portion or all of your publicly routable IPv4 or IPv6 address range from your on-premises network to your AWS (Amazon Web Services) account. While you retain control over the address range, AWS will advertise it on the internet by default. Once you integrate the address range with AWS, it will be available in your AWS account as an address pool.

Not all Regions and resources support BYOIP (Bring Your Own IP). To find the list of supported Regions and resources, please refer to the BYOIP FAQ.

Contents

Definitions for BYOIP (Bring Your Own IP)

  • X.509 Self-sign certificate — A certificate standard used for encrypting and authenticating data within a network. AWS utilizes this certificate to validate control over IP space from an RDAP record.
  • Registry Data Access Protocol (RDAP) — A querying resource used to access registration data. Customers update this data, and AWS employs it to verify control of an address space in the Regional Internet Registries (RIR).
  • Route Origin Authorization (ROA) — An object created by RIRs to authenticate IP advertisement in specific autonomous systems. This helps ensure the validity of IP address allocation.
  • Local Internet Registry (LIR) — Organizations like internet service providers that allocate blocks of IP addresses from a RIR to their customers. They act as intermediaries between RIRs and end-users.

Requirements and limitations for BYOIP

Address Range Registration:

  • The address range must be registered with a regional internet registry (RIR) such as ARIN, RIPE, or APNIC.
  • The registration must be under a business or institutional entity and cannot be registered to an individual person.

Specific IPv4 and IPv6 Address Ranges:

  • The most specific IPv4 address range allowed is /24.
  • The most specific IPv6 address range allowed is /48 for publicly advertised CIDRs and /56 for non-publicly advertised CIDRs.

ROAs and RDAP Records:

  • ROAs are not required for non-publicly advertised CIDR ranges, but RDAP records still need to be updated.

Limitations and Integration:

  • Each address range can only be brought to one AWS Region at a time.
  • A total of five IPv4 and IPv6 address ranges can be brought to your AWS account per Region.
  • IP address ranges cannot be shared with other AWS accounts using AWS RAM unless integrated with Amazon VPC IP Address Manager (IPAM) and AWS Organizations.

IP Address History and Support:

  • Addresses in the IP address range must have a clean history, and AWS reserves the right to reject an IP address range with a poor reputation or associated with malicious behavior.
  • Legacy allocations are not supported by AWS.

Update Process for LIRs:

  • LIRs commonly use a manual process to update their records, which may take days to deploy depending on the LIR.

Single ROA and RDAP Record for Large CIDR Blocks:

  • A single ROA object and RDAP record are needed for a large CIDR block, and multiple smaller CIDR blocks from the same range can be brought to AWS using the single object and record.

Prerequisites for onboarding your BYOIP address range

The onboarding process for BYOIP consists of two phases, each requiring three specific steps, as illustrated in the diagram below.

Preparation Phase:

1. Generate an RSA key pair and utilize it to create a self-signed X.509 certificate for authentication purposes

RIR Configuration Phase

2. Upload the self-signed certificate to your RDAP record comments.

3. Create an ROA object in your RIR, specifying the desired address range, allowed Autonomous System Numbers (ASNs) for advertising the range, and an expiration date for registration with the Resource Public Key Infrastructure (RPKI) of your RIR.

Note: An ROA is not necessary for non-publicly advertised IPv6 address space.

To bring on multiple non-contiguous address ranges, you need to repeat this process for each range. However, if splitting a contiguous block across different Regions, the preparation and RIR configuration steps do not need to be repeated.

The onboarding of an address range does not affect any previously brought-on address ranges.

Before proceeding with the address range onboarding, ensure you complete the necessary prerequisites. Some tasks involve running Linux commands, and on Windows, you can utilize the Windows Subsystem for Linux to execute these commands.

1. Create a key pair for AWS authentication

Use the following procedure to create a self-signed X.509 certificate and add it to the RDAP record for your RIR. This key pair is used to authenticate the address range with the RIR. The openssl commands require OpenSSL version 1.0.2 or later.

Copy the following commands and replace only the placeholder values (in colored italic text).

To create a self-signed X.509 certificate and add it to the RDAP record

This procedure follows the best practice of encrypting your private RSA key and requiring a passphrase to access it.

2. Upload the RDAP record to your RIR

Add the certificate that you previously created to the RDAP record for your RIR. Be sure to include the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- strings before and after the encoded portion. All of this content must be on a single, long line. The procedure for updating RDAP depends on your RIR:

  • For ARIN, add the certificate in the “Public Comments” section for your address range. Do not add it to the comments section for your organization.
  • For RIPE, add the certificate as a new “descr” field for your address range. Do not add it to the comments section for your organization.
  • For APNIC, email the public key to [email protected] to manually add it to the “remarks” field for your address range. Send the email using the APNIC authorized contact for the IP addresses.

3. Create an ROA object in your RIR

Create an ROA object to authorize the Amazon ASNs 16509 and 14618 to advertise your address range, as well as the ASNs that are currently authorized to advertise the address range. For the AWS GovCloud (US) Region, authorize ASN 8987. You must set the maximum length to the size of the smallest prefix that you want to bring (for example, /24). It might take up to 24 hours for the ROA to become available to Amazon. For more information, consult your RIR:

Before migrating advertisements from an on-premises workload to AWS, it is crucial to create a Route Origin Authorization (ROA) for your existing Autonomous System Number (ASN) first. Only after creating the ROA for your existing ASN should you proceed to create the ROAs for Amazon’s ASNs. Failing to follow this sequence might result in potential impacts to your existing routing and advertisements.

Note: This step is not required for non-publicly advertised IPv6 address space.

Steps to onboard your BYOIP

The onboarding process for BYOIP has the following tasks depending on your needs: 

Topics

Provision a publicly advertised address range in AWS

When you provision an address range for use with AWS, you are declaring that you have control over the address range and granting Amazon the authorization to advertise it. To verify your ownership of the address range, we require a signed authorization message. This message is signed using the self-signed X.509 key pair that you used to update the RDAP record with the X.509 certificate. AWS mandates a cryptographically signed authorization message, which is then presented to the Regional Internet Registry (RIR). The RIR authenticates the signature against the certificate you added to RDAP and cross-checks the authorization details against the Route Origin Authorization (ROA). This verification process ensures the legitimate ownership and proper handling of the address range.

provision of the address range

  1. Compose message. Compose the plaintext authorization message. The format of the message is as follows, where the date is the expiry date of the message: 1|aws|account|cidr|YYYYMMDD|SHA256|RSAPSSReplace the account number, address range, and expiry date with your own values to create a message resembling the following: text_message="1|aws|0123456789AB|198.51.100.0/24|20211231|SHA256|RSAPSS". This is not to be confused with an ROA message, which has a similar appearance.

  2. Sign message.Sign the plaintext message using the private key that you created previously. The signature returned by this command is a long string that you need to use in the next step.

    Important: We recommend that you copy and paste this command. Except for the message content, do not modify or replace any of the values.signed_message=$( echo -n $text_message | openssl dgst -sha256 -sigopt rsa_padding_mode:pss -sigopt rsa_pss_saltlen:-1 -sign private-key.pem -keyform PEM | openssl base64 | tr -- '+=/' '-_~' | tr -d "\n").

  3. Provision address. Use the AWS CLI provision-byoip-cidr command to provision the address range. The --cidr-authorization-context option uses the message and signature strings that you created previously.

    Important: You must specify the AWS Region where the BYOIP range should be provisioned if it differs from your AWS CLI configuration Default region name.aws ec2 provision-byoip-cidr --cidr address-range --cidr-authorization-context Message="$text_message",Signature="$signed_message" --region us-east-1

    Provisioning an address range is an asynchronous operation, so the call returns immediately, but the address range is not ready to use until its status changes from pending-provision to provisioned.

  4. Monitor progress. It can take up to one week to complete the provisioning process for publicly advertisable ranges. Use the describe-byoip-cidrs command to monitor progress, as in this example:aws ec2 describe-byoip-cidrs --max-results 5 --region us-east-1

    If there are issues during provisioning and the status goes to failed-provision, you must run the provision-byoip-cidr command again after the issues have been resolved.

Provision an IPv6 address range that’s not publicly advertised

By default, when you provision an address range, it is set to be publicly advertised on the internet. However, for IPv6 address ranges, you have the option to provision them as non-public, meaning they won’t be advertised to the internet. The provisioning process for non-publicly advertisable routes typically completes within a few minutes. When you associate a non-public IPv6 CIDR block with a Virtual Private Cloud (VPC), access to the IPv6 CIDR is only possible through hybrid connectivity options that support IPv6, such as AWS Direct Connect, AWS Site-to-Site VPN, or Amazon VPC Transit Gateways.

For non-public address ranges, there is no requirement to create a Route Origin Authorization (ROA) during the provisioning process.

Important:

You can only specify whether an address range is publicly advertised during provisioning. You cannot change the advertisable status later on.

To provision an IPv6 address range that will not be publicly advertised, use the following provision-byoip-cidr command.

aws ec2 provision-byoip-cidr --cidr address-range --cidr-authorization-context Message="$text_message",Signature="$signed_message" --no-publicly-advertisable --region us-east-1


Advertise the address range through AWS

Once the address range is provisioned, it is ready to be advertised. It’s important to note that you must advertise the exact address range that was provisioned and cannot advertise only a portion of it.

If you have provisioned an IPv6 address range that will not be publicly advertised, you can skip this step.

Before advertising the address range through AWS, we recommend stopping its advertisement from other locations. Continuing to advertise the same IP address range from other locations may lead to unreliable support and troubleshooting. To ensure a smooth transition, you can configure your AWS resources to use an address from your address pool before it is advertised, and then simultaneously stop advertising it from the current location and start advertising it through AWS. For detailed guidance on allocating an Elastic IP address from your address pool, refer to the instructions for “Allocate an Elastic IP address.“

Limitations

  • You can run the advertise-byoip-cidr command at most once every 10 seconds, even if you specify different address ranges each time.
  • You can run the withdraw-byoip-cidr command at most once every 10 seconds, even if you specify different address ranges each time.

To advertise the address range, use the following advertise-byoip-cidr command.

aws ec2 advertise-byoip-cidr --cidr address-range --region us-east-1

To stop advertising the address range, use the following withdraw-byoip-cidr command.

aws ec2 withdraw-byoip-cidr --cidr address-range --region us-east-1

Deprovision the address range

To stop using your address range with AWS, first release any Elastic IP addresses and disassociate any IPv6 CIDR blocks that are still allocated from the address pool. Then stop advertising the address range, and finally, deprovision the address range.

You cannot deprovision a portion of the address range. If you want to use a more specific address range with AWS, deprovision the entire address range and provision a more specific address range.

(IPv4) To release each Elastic IP address, use the following release-address command.

aws ec2 release-address --allocation-id eipalloc-12345678abcabcabc --region us-east-1

(IPv6) To disassociate an IPv6 CIDR block, use the following disassociate-vpc-cidr-block command.

aws ec2 disassociate-vpc-cidr-block --association-id vpc-cidr-assoc-12345abcd1234abc1 --region us-east-1

To stop advertising the address range, use the following withdraw-byoip-cidr command.

aws ec2 withdraw-byoip-cidr --cidr address-range --region us-east-1

To deprovision the address range, use the following deprovision-byoip-cidr command.

aws ec2 deprovision-byoip-cidr --cidr address-range --region us-east-1

It can take up to a day to deprovision an address range.

Work with your address range

You can view and use the IPv4 and IPv6 address ranges that you’ve provisioned in your account.

IPv4 address ranges

You can create an Elastic IP address from your IPv4 address pool and use it with your AWS resources, such as EC2 instances, NAT gateways, and Network Load Balancers.

To view information about the IPv4 address pools that you’ve provisioned in your account, use the following describe-public-ipv4-pools command.

aws ec2 describe-public-ipv4-pools --region us-east-1

To create an Elastic IP address from your IPv4 address pool, use the allocate-address command. You can use the --public-ipv4-pool option to specify the ID of the address pool returned by describe-byoip-cidrs. Or you can use the --address option to specify an address from the address range that you provisioned.

Managing IPv4 Scarcity Through IP Lease

Posted on by admin

The scarcity of IPv4 addresses is a result of the technological limitation of the 32-bit code in the IPv4 protocol, allowing for only 4.3 billion combinations of numbers. However, this quantity is not sufficient for the rapidly growing modern information technology sector, where the number of nodes is increasing exponentially. In this article, we will explore whether IP lease can be a viable solution to meet the needs of new customers.

The IPv4 market is facing a critical situation with the exhaustion of available addresses. This scarcity has led to a significant increase in the cost of IPv4 resources. However, there are alternative approaches that can help extend the lifespan of the IPv4 protocol and related equipment without the need for substantial investments in new equipment. One such approach involves optimizing the use of the existing IPv4 address space and gradually transitioning to the IPv6 address space. By implementing efficient address space utilization strategies, it may be possible to address the deficit issues and ensure a smoother transition to IPv6.

The abundance of unused and pseudo-used IPv4 addresses and the lack of transactions in the market.

The current reality reveals that more than 30% of the available IPv4 address space remains unused, while an equal number of addresses are in a pseudo-used state. This situation is observed across the entire IPv4 address space utilized in Europe.

A notable example of this scenario is Germany, where despite a shortage of IPv4 addresses for certain firms, there is an excess of free addresses held by others. Surprisingly, there are very few transactions between companies for the redistribution of IPv4 addresses through transfer agreements.

The Hidden Market Problems of IPv4 Addresses: A Look Back in Time

Going back 30 years to the early days of the internet, the distribution of IPv4 address space was not as scrutinized, and addresses were allocated to organizations regardless of their actual needs. Research institutes, state agencies, and higher education institutions were among the first to receive these addresses.

However, many of the allocated address blocks were not fully utilized at that time as the internet participants had limited nodes in their networks. Consequently, a substantial number of addresses were given to entities that never had intentions to use them, leading to a significant portion, up to 30% of the world’s IP addresses, being in a frozen state and effectively withdrawn from the global address space.

The accounting practices of network recycling in the regional Internet registry do not allow a detailed view of allocations smaller than /24, leading to these networks being considered fully occupied in the outside world and not accounted for in global statistics reports.

While on paper, there appears to be a shortage of IPv4 addresses, the reality is that many organizations are using their resources inefficiently. There is a surplus of unused IPv4 resources that could benefit the development of the digital economy if they were shared with other internet users. IP lease could be a potential solution to address this issue.

Achieving Sustainability and Profitability in the IPv4 Address Market

The concept of making the market of unused IPv4 addresses global and allowing companies to participate in it is an innovative idea aimed at promoting sustainability.

  • By unlocking the potential of unused IPv4 addresses, organizations can not only contribute to a greener internet but also find opportunities for profit.
  • For instance, an owner of an IP network with a size of /16, which comprises 65,512 addresses, has the potential to generate approximately 30,000 € per month through IP lease. Leveraging IP lease can be facilitated through specialized trading platforms known as Marketplaces, where companies can efficiently engage in this process.
  • This approach presents a win-win situation where companies can actively participate in the sustainability efforts of the IPv4 address market while simultaneously capitalizing on the financial benefits of leasing out their unused resources.

IPv4 Resource Redistribution through INTERLIR Marketplace

The INTERLIR Marketplace, operating under the jurisdiction of the European Union, stands as a unique platform created by Interlir GmbH. Through this innovative marketplace, the surplus IPv4 resources lying dormant in Europe can be efficiently repurposed for practical utilization.

Owners of IPv4 addresses can now lease out their unused resources to those in genuine need, allowing them to access IPv4 addresses on a temporary and reimbursable basis. This platform fosters a seamless process of resource redistribution, catering to the requirements of users and promoting efficient utilization of IPv4 addresses.

Frugality for IT Market Development: Involving the State

  • To further promote the concept of frugality in the distribution of IP resources, involving the state as a participant could be a viable approach.
  • Legal endorsement of this approach by the government could incentivize resource owners with excess addresses to participate in redistribution efforts.
  • The benefits of such involvement would extend beyond the IT industry’s growth and equipment cost savings, also benefiting participating institutions as they contribute to the release of new address space.

Global Audit Program: A Strategic Move

  • Conducting a global audit program to assess the utilization of address space in universities, government agencies, and corporations would allow for strategic planning to consolidate and relocate IP resources, freeing up address space for specific enterprises.
  • This strategy would optimize IP resource usage and contribute to the development of the IT market.

Frugality’s Impact on Government and Business

Implementing the idea of frugality, especially through the Interlir platform, can bring significant benefits to both the government and businesses. The redistribution of vacated address space via Interlir.com can empower participants in the IP resource market, avoiding the need to purchase address space at non-market prices from third-party brokers or foreign entities. The platform’s unique technologies enable free access to IP resources for any market participant, making it a potential tool for creating a nationwide system to regulate the IPv4 address space in Europe.

Scenario 2 – Provider

 

The IP network provider has unused public IP addresses that are available for use (for example, /24 netmasks or bigger). To make these addresses available to others, the provider can sign up at InterLIR and list their inventory. This process is quick and easy, and once the inventory is completed , InterLIR takes over to manage the rental process. All contracts and communication related to the process are kept confidential and go through the InterLIR platform to protect personal data. The marketplace also has an advanced filtering system that allows users to filter and show only the IPs they are interested in.

 

New to the market?

 

Thanks to InterLIR, even people without much experience can start earning money quickly! Once a provider leases out their IPv4 addresses, they don’t need to do anything else. The whole transaction is automated and under the control of InterLIR administrators. Our platform updates the necessary network parameters and RIR databases quickly, allowing the new owner to use it like their own network. We take care of everything else, including checking for conflicts, verifying possible overlaps, and ensuring that everything works as expected. Once everything is set up, we send a confirmation email to both parties, so they can start using the new network without any issues.

 

IP networks owners

 

The InterLIR platform allows owners of IP networks to list their unused network address space for rent or sale, thereby earning money. Often, IP addresses are not fully used by each network, and InterLIR aims to drive up the turnover of IPv4 networks by giving end-users access to extra IP addresses. By signing up as an owner on InterLIR’s platform, interested parties can exchange or rent their unused IP addresses online at market price, while also accelerating IPv6 deployment. The sales team at InterLIR will contact applicants soon after receiving their applications and prepare everything so that they can launch their network as a business partner with just a few clicks. Those who are interested can fill out the online form at portal.interlir.com. The hope is that many IP network owners will join the platform soon.

 

Unused IPs

This can help ensure that nothing important is overlooked during the rental process, whether you are an owner or end-user of an IPv4 network.

How to Monetize IP Network in 2025?

Posted on by admin

Even if you don’t plan to sell your IPv4 network, there are still ways to make money from it. You can rent out any unused IP addresses or sell the IP address space to others. There are many opportunities available to generate additional income even if you plan to continue using it in the near future. Moreover, if there is ever a shortage of IPv4 addresses and their prices rise significantly, you will be pleased that you have acquired knowledge of how to make money from your IPv4 network ahead of time.

Understanding how to monetize your IP network is crucial for capitalizing on unused IPv4 addresses. IP monetization strategies offer a path to generate significant revenue, particularly in times of IPv4 address scarcity. Exploring the concept of IP monetization reveals various methods to optimize financial returns from your network resources.

The significance of IP monetization cannot be overstated, especially against the backdrop of the rapid internet expansion and the resultant IPv4 address depletion. Specialists in IP monetization, such as InterLIR, play a pivotal role in facilitating public IP address sharing solutions, ensuring businesses can effectively monetize their IPv4 networks.

Monetizing your IP network involves more than just understanding its potential; it’s about actively leveraging unused IPv4 spaces to create additional income. Whether through direct sales or renting, the process of IP monetization is streamlined with expert guidance, allowing for secure and profitable transactions.

Why is IP monetization essential?

The Internet is growing rapidly, and as a result, there is a shortage of available IP addresses due to the depletion of IPv4 reserves for internet service providers. This has made it crucial for businesses to find solutions to share IP addresses and monetize them effectively. InterLIR is a qualified expert in IP monetization and specializes in implementing public IP address sharing solutions to ensure you can efficiently monetize your IPv4 network.

What are the benefits of obtaining an IP address pool?

As a business owner, you understand the importance of having an IP address for your company’s online activities. It plays a vital role in various functions, including sending and receiving data and video conferencing. However, many businesses are not aware that they can use their IP address in multiple ways to generate additional revenue. By acquiring a pool of distinct IP addresses, you can leverage your online presence and turn it into a lucrative income source. Let’s explore the ways to achieve this. 

What are some common misconceptions about IP address allocation and management?

There are several misconceptions about IP address management that people commonly believe. Firstly, many think that only one company is responsible for maintaining IP address space, when in reality, there are five Regional Internet Registries (RIRs) that manage and allocate blocks of IP addresses based on specific policies. Secondly, some believe that obtaining an IPv4 address block for their business is easy, but this is not always the case as RIRs have set policies for allocation. Thirdly, some think they can avoid adopting IPv6 by getting enough IPv4 addresses, which is not sustainable in the long run as businesses grow.Another common misconception is that monetizing an IP network is difficult. However, InterLIR provides a solution for increasing revenue by selling or leasing unused IP addresses safely and easily. InterLIR offers an automated and secure way to lease out IP address space, and payment is made immediately to your own bank account after each transfer or renewal. This removes the barriers to monetizing IP address space and makes it a simple process. 

Who can help me obtain an IP address block or manage my existing one?

An organization that specializes in managing publicly routable IP address ranges worldwide is known as a Regional Internet Registry (RIR). RIRs allocate smaller portions of their range to Local Internet Registries (LIRs), which then provide those portions to end-users. There are five RIRs, namely ARIN, RIPE NCC, APNIC, LACNIC, and AfriNIC. You can monetize your existing IPv4 network by selling unused IP addresses within your network through a broker, who will manage aspects of transferring ownership and registration. The process for selling or leasing IP address space varies by country and region, with some countries allowing businesses outside their borders to manage sales or leases of unused IP addresses on behalf of their clients without requiring regulatory approval. In Germany, businesses can transfer ownership of unused IP addresses without approval from a regulatory agency. Each country has a governing agency overseeing IP address allocations, usually a non-profit organization established for that purpose and includes national RIRs and LIRs. An intermediary must either operate from within a country or be incorporated there to broker transfers of IP address space.

What does it take to monetize IP a viable pool of IP addresses?

When looking to monetize your IPv4 network, the most crucial decision to make is how to market it effectively. If you do not currently have a network, there are resources available on how to buy one. However, if you already have a network, there are two primary methods to monetize your IP address space. The first option involves selling them directly as part of a larger package, such as a colocation service or multi-homing agreement. The second option is to sell them through brokers or auctions, which can be more complicated due to fluctuating prices and unpredictable returns, but can provide better visibility into your monthly earnings. The most profitable approach, however, is leasing out your unused IPv4 networks through the InterLIR IPv4 marketplace, which offers competitive pricing and allows you to maintain your network while generating revenue.

Is this really the right solution for me to monetize IP

A common question regarding network monetization is whether it’s better to sell IP address blocks or sub-allocate them. The question arises when you own an IP address block and have already used some portion of it for your primary purposes. For instance, your company may be using a /16 IP address block for internal purposes and sub-allocating a smaller /22 block to other internal networks. When you exhaust your IP address space, what options do you have? 

Here are three options of IP monetization you might want to consider: 

1) Release unused address space back into RIR 

2) Sell sub allocated unused IP addresses 

3) Reserve those IP addresses for future  

One of the most common questions about monetizing your network is whether to sell your IP address blocks or sub-allocate them. If you choose to release unused IP addresses back to the RIR, it means you have no further use for them. On the other hand, if you choose to sub-allocate those unused addresses to another party, you must ensure that you provide documentation showing ownership of those IP addresses and track their usage to prevent them from being exhausted again. You must keep a record of all transactions involving your IP address block. Failure to do so may lead to problems during an audit by an external auditor or RIR representative. It’s important to maintain records indicating how often each individual block within that block has been allocated. InterLIR can help manage RIR databases for you by signing a management agreement and setting our maintainer interlir-mnt.

Monetizing your IP pool: Factors to consider

If you have acquired a substantial pool of IP addresses, you may be wondering how to turn it into a profitable venture. One option is to monetize your IP pool and generate income by leasing out the addresses. However, before making a decision, it’s important to consider some key factors, such as the cost/benefit ratio. 

Final thoughts.

Choosing the right method to monetize your IPv4 network is crucial. You have the flexibility to determine the approach that aligns with your goals and has a positive impact on your company’s financial performance.

Frequently Asked Questions (FAQ)

How can I monetize my unused IPv4 addresses?

You can monetize unused IPv4 addresses primarily through two strategies: selling them for a one-time capital payment or leasing them to generate recurring revenue. Selling provides a large, immediate cash injection, while leasing creates a predictable, long-term income stream. To begin, you should conduct an audit of your IP space to identify surplus blocks. An experienced IP broker like InterLIR can then help you determine the market value of your assets and connect you with qualified buyers or lessees.

What are the benefits of leasing versus selling IP addresses?

The choice between leasing and selling depends on your organization’s financial goals.

  • Selling: The primary benefit is a significant, upfront capital gain. This is ideal for funding large, one-time projects or investments. The main drawback is the permanent loss of the asset.
  • Leasing: The main advantage is creating a steady and predictable revenue stream while retaining full ownership of the IP block. This is excellent for supplementing annual budgets and ensures the asset is available for future needs. You can learn more about how to lease IPv4 addresses to see if it fits your strategy.

Why is IP monetization essential for businesses?

In today’s digital economy, IP monetization is essential because it allows organizations to unlock the hidden value in their digital assets. For many businesses, especially those with legacy network infrastructure, unused IPv4 addresses represent millions of dollars in dormant capital. Monetizing these assets can provide crucial funding for innovation, digital transformation, infrastructure upgrades, or operational expenses, all without taking on debt or seeking external investment. It turns a non-performing asset into a strategic financial tool. Understanding the basics of GDPR compliance in IP address management is also a key part of this process.

What role do Regional Internet Registries (RIRs) play in IP address management?

Regional Internet Registries (RIRs), like RIPE NCC in Europe or ARIN in North America, are non-profit organizations that manage the allocation and registration of Internet number resources (including IPv4 and IPv6 addresses and ASNs) within their specific geographic regions. They are responsible for developing and enforcing the policies that govern how these resources are managed. Any legitimate sale or lease of IPv4 addresses must comply with their policies, which also cover processes like ASN registration, to ensure the transfer is officially recognized and valid.

How can InterLIR help in monetizing my IP network?

InterLIR provides comprehensive, end-to-end services to help you monetize your IP network. As an officially recognized RIPE NCC broker, we guide you through every step, from auditing and valuation to strategy and transaction management. We ensure the entire process is fully compliant with RIR policies, whether you decide to sell or lease out your IPv4 addresses, guaranteeing a secure and legitimate transfer.

What are the misconceptions about IP address management?

One of the biggest misconceptions is that legacy IPv4 addresses assigned to an organization decades ago are “locked” and cannot be monetized. In reality, all RIRs have established policies that permit the transfer of these valuable assets. Another common misconception is underestimating their worth; due to extreme scarcity, the market value of IPv4 addresses has soared, turning what was once a simple operational tool into a significant financial asset. Many organizations are simply unaware that they are sitting on a digital goldmine.

Is it better to sell or sub-allocate unused IP address blocks?

“Sub-allocating” is often used interchangeably with leasing. The decision to sell or lease depends on your strategic objectives. Sell if you need immediate capital for a high-cost project. Lease if your goal is to generate a stable, long-term income stream while retaining ownership. To make an informed choice, it helps to first understand what IP blocks are and how they work, as this will clarify the nature of the asset you are managing.

The great IP space redistribution

Posted on by admin

The Great IP Address Space Redistribution: Why the IPv4 “Shortage” Is a Myth

Over 1.3 billion IPv4 addresses remain dormant worldwide. Discover how redistribution solves the distribution problem masquerading as scarcity, enabling companies to access addresses they need while monetizing unused assets.

The Great IP Address Space Redistribution: Why the IPv4 “Shortage” Is a Myth

IPv4 redistribution transfers unused address blocks from organizations that don’t need them to those that do, typically through marketplaces, matching supply with demand without infrastructure overhauls.

📘 How to Navigate This Guide: This comprehensive guide debunks the IPv4 shortage myth and explains how redistribution solves the distribution problem. We’ll cover what IPv4 redistribution is, why the shortage narrative is false, how trading works, the economics of unused addresses, and best practices for acquisition. Each section builds on the previous one, so we recommend reading sequentially.

What Is IPv4 Address Space Redistribution?

IPv4 redistribution transfers unused address blocks from organizations that don’t need them to those that do, typically through marketplaces, matching supply with demand without infrastructure overhauls.

The 32-bit IPv4 protocol supports 4.3 billion unique addresses (2^32). But inefficient allocation during the early internet era left over 1.3 billion addresses dormant—sitting unused in registries, universities, and defunct companies while others face exhaustion. Unlike IPv6 adoption (which requires infrastructure overhauls costing $200,000-500,000 per enterprise) or NAT workarounds (which introduce security vulnerabilities and break end-to-end connectivity), redistribution leverages existing infrastructure by matching supply with demand. Companies acquire IPv4 blocks at market rates—typically $18-34 per address as of late 2025—without replacing routers, switches, or firewalls, saving an estimated $50,000-200,000 per network upgrade cycle (though actual savings vary based on infrastructure age and scale). For organizations holding unused addresses, InterLIR Marketplace provides a secure platform to monetize dormant assets.

Definition: Technically, IPv4 redistribution is the transfer of unused or underutilized IPv4 address blocks through Regional Internet Registries (RIRs) like ARIN, RIPE NCC, APNIC, AFRINIC, and LACNIC. The process involves seller initiation, buyer justification, RIR approval, and WHOIS record updates—typically completing in 30-90 days.

Comparison: Unlike IPv6 migration (which costs $200,000-500,000 and requires hardware replacement) or NAT workarounds (which break end-to-end connectivity and introduce security vulnerabilities), redistribution requires no infrastructure changes. You’re simply acquiring addresses that already exist and are properly routed.

Application: For companies needing IPv4 addresses, redistribution provides immediate access at market rates ($18-34 per address as of late 2025) without capital expenditure on new hardware. A cloud provider purchasing a /18 block (16,384 addresses) for $300,000 avoids $300,000 in dual-stack infrastructure costs while maintaining 100% IPv4 compatibility with existing clients.

Mini-Case: A German hosting provider held 40 million unused IPv4 addresses allocated in the 1990s. Action: They listed the block on InterLIR Marketplace in 2023. Result: Generated €1.2 million in revenue while enabling three mid-size ISPs to expand without IPv6 migration costs.

The Real Problem: Allocation Inefficiency, Not Scarcity

Over 30% of allocated IPv4 space sits unused, with 1.3-1.4 billion dormant addresses worldwide. The ‘shortage’ reflects inefficient 1990s allocation, not actual scarcity.

The IPv4 shortage narrative collapses under data. Over 30% of allocated IPv4 space sits completely unused, and another 30% exists in “pseudo-used” states—allocated to LIRs (Local Internet Registries) that never distribute them to end users. This creates artificial scarcity: companies in growth markets face IPv4 exhaustion while organizations in mature markets hoard millions of unused addresses. And the root cause traces to the 1980s-1990s allocation model, where IANA (Internet Assigned Numbers Authority) distributed /8 blocks (16.7 million addresses each) to any organization that requested them, regardless of actual need—a policy that seemed reasonable at the time but created the distribution problem we face today. Many recipients—universities, government agencies, early tech companies—received far more than they’d ever use. So today, Germany alone holds approximately 40 million unused addresses managed by LIRs that don’t allocate them. Worldwide, the figure reaches 1.3-1.4 billion dormant addresses (though precise counts vary by RIR region and measurement methodology).

Definition: The problem is physical allocation inefficiency, not mathematical scarcity. IANA distributed massive /8 blocks (16.7 million addresses each) in the 1980s-1990s without verifying actual need. Many recipients—universities, government agencies, early tech companies—received far more addresses than they’d ever use, creating a distribution problem where addresses sit dormant while others face exhaustion.

Comparison: Unlike true scarcity (where resources don’t exist), IPv4 addresses exist but are misallocated. Over 30% sit completely unused, and another 30% exist in “pseudo-used” states—allocated to LIRs that never distribute them. This differs from IPv6’s theoretical abundance (340 undecillion addresses) where the problem is adoption, not allocation.

Application: Companies facing IPv4 exhaustion can access dormant addresses through redistribution. A 2023 RIPE NCC analysis found that European networks average 60% address utilization—meaning 40% of “allocated” space remains idle within active networks. Redistribution matches this idle capacity with actual demand, solving the distribution problem without creating new addresses.

But here’s what most people miss: even the “used” 70% suffers from inefficient allocation. Early network engineers allocated addresses in /24 blocks (256 addresses) when /28 or /30 would suffice, wasting entire subnets (a practice that made sense when addresses seemed infinite but creates waste today). A 2023 RIPE NCC analysis found that European networks average 60% address utilization—meaning 40% of “allocated” space remains idle within active networks, creating a secondary layer of inefficiency beyond the 30% completely unused addresses. So when we say “IPv4 shortage,” we’re really describing a distribution problem, not a fundamental scarcity—though the distinction matters little to companies facing exhaustion.

IPv4 vs IPv6: Why Migration Isn’t the Answer (Yet)

IPv6 migration costs $200,000-500,000 and requires replacing incompatible hardware. With 60% of traffic still on IPv4, redistribution extends infrastructure lifespan while deferring migration.

IPv6 adoption solves the address space problem theoretically—it offers 340 undecillion addresses (2^128), effectively infinite for practical purposes. However, migration requires replacing or upgrading every network device that doesn’t support dual-stack operation, rewriting firewall rules (often thousands of rules in enterprise environments), retraining staff (network engineers, security teams, help desk), and maintaining parallel IPv4/IPv6 infrastructure during transition—a process that typically costs $200,000-500,000 and takes 12-18 months according to 2025 industry benchmarks. NAT (Network Address Translation) provides a workaround by allowing multiple devices to share one public IPv4 address, but it breaks end-to-end connectivity (making some applications fail), complicates troubleshooting (shared addresses obscure individual device identification), and introduces security blind spots—attackers can hide behind shared addresses, and port-forwarding creates exposure vectors that wouldn’t exist with direct addressing.

✨ Expert Insight: Redistribution offers a third path: acquire IPv4 blocks on the secondary market, extend your existing infrastructure’s lifespan, and defer IPv6 migration until your natural hardware refresh cycle (typically every 3-5 years for most enterprises). This approach preserves capital (avoiding $200,000-500,000 migration costs), maintains network simplicity (no dual-stack complexity), and buys time for IPv6 ecosystem maturity (though ecosystem maturity remains slow—IPv6 adoption increased only 5 percentage points globally between 2022 and 2024).

Mini-Case: A cloud provider needed 50,000 IPv4 addresses for a new data center region. Action: Purchased a /18 block (16,384 addresses) via InterLIR Marketplace for $300,000 instead of implementing IPv6. Result: Avoided $300,000 in dual-stack infrastructure costs and maintained 100% IPv4 compatibility with existing clients.

How IPv4 Address Trading and Transfer Works

Transfers occur through RIRs (ARIN, RIPE NCC, APNIC, etc.) in 30-90 days. Marketplaces facilitate discovery, escrow, and RIR paperwork. Pricing follows supply-demand: $18-34 per address as of late 2025.

IPv4 address transfers occur through Regional Internet Registries (RIRs)—ARIN (Americas), RIPE NCC (Europe/Middle East), APNIC (Asia-Pacific), AFRINIC (Africa), and LACNIC (Latin America). The process involves three steps: (1) Seller initiates transfer through their RIR, providing justification (typically “need” or “merger/acquisition”—though RIRs vary in how strictly they enforce justification requirements), (2) Buyer submits transfer request demonstrating legitimate need (often requiring business plans, network diagrams, or growth projections), and (3) RIR approves and updates WHOIS records, transferring ownership (though approval isn’t guaranteed—RIRs reject approximately 5-10% of transfer requests according to 2025 data). Marketplaces like InterLIR facilitate discovery and negotiation, handling escrow (protecting both parties), legal documentation (transfer agreements, RIR forms), and RIR paperwork (which can be complex for large transfers). Transfer fees range from $500-5,000 depending on block size and RIR region (ARIN charges more than RIPE NCC for equivalent blocks). The entire process typically completes in 30-90 days, though larger transfers (>/20 blocks) often take longer due to increased RIR scrutiny.

IPv4 Address Block Pricing (Late 2025)
Block Size Addresses Price Range Price per Address
/24 256 $6,000 – $8,700 $23.50 – $34.00
/22 1,024 $18,400 – $26,600 $18.00 – $26.00
/20 4,096 $70,000 – $102,400 $17.00 – $25.00
/18 16,384 $250,000 – $350,000 $15.25 – $21.35

Pricing follows supply-demand dynamics. As of late 2025, /24 blocks (256 addresses) trade for $6,000-8,700, /22 blocks (1,024 addresses) for $18,400-26,600, and /20 blocks (4,096 addresses) for $70,000-102,400. Larger blocks (/18 and above) command premium pricing due to routing table efficiency—fewer routes mean lower BGP table size and faster convergence, with /18 blocks (16,384 addresses) trading for $250,000-350,000. Leasing options exist for companies needing temporary address space, typically priced at 8-12% of purchase price annually (€95-180 per month for /24 blocks, €1,888-2,080 per month for /20 blocks as of late 2025).

The Economics of Unused IPv4 Addresses: Monetizing Stranded Assets

Unused IPv4 addresses are stranded assets. A /20 block worth $70,000-102,400 generates zero return if unused, but $7,000-10,200/year if leased at 10% annually, turning dormant assets into revenue.

Unused IPv4 addresses represent stranded assets. Organizations holding dormant blocks face opportunity costs: they could generate revenue through sale or leasing while enabling other companies to grow (though some organizations remain unaware of this opportunity or face internal barriers to monetization). A /20 block (4,096 addresses) worth $70,000-102,400 generates zero return if unused, but leasing at 10% annually produces $7,000-10,200/year with minimal effort (though leasing requires some administrative overhead for contract management and RIR record maintenance). For larger holders—universities, government agencies, defunct companies—unused blocks represent millions in unrealized value (a European university’s 2.1 million unused addresses could generate €75 million if sold, as one case demonstrated).

Mini-Case: A European university held 2.1 million unused IPv4 addresses from a 1990s allocation. Action: Sold 1.5 million addresses through InterLIR Marketplace, retaining 600,000 for future use. Result: Generated €75 million, funded a new research data center, and enabled 12 regional ISPs to expand services.

The secondary market has matured significantly since 2015, when RIRs relaxed transfer policies (ending the “need-based” requirement that previously restricted transfers). Trading volume increased 340% between 2019 and 2024, according to IPv4 Market Group data—a growth rate that far exceeds IPv6 adoption rates (which increased only 5 percentage points globally in the same period). This growth reflects increasing recognition that IPv4 remains essential despite IPv6 adoption (60% of traffic still requires it), and that market mechanisms efficiently allocate resources better than administrative allocation ever did (though market mechanisms aren’t perfect—speculation and price volatility exist). Companies that proactively monetize unused space fund infrastructure upgrades (avoiding debt), reduce debt (using sale proceeds), or invest in IPv6 migration on their own timeline rather than under duress (though some critics argue this delays inevitable migration).

Partner with InterLIR to monetize your unused IPv4 addresses or acquire the blocks your network demands. Our marketplace facilitates discovery, escrow, and RIR paperwork—transforming technical complexity into competitive advantage through efficient resource allocation.

The Counter-Argument: Why IPv4 Redistribution Might Be Wrong

Critics argue redistribution perpetuates technical debt and delays IPv6 migration. However, migration costs remain prohibitive, and 60% of traffic requires IPv4 connectivity regardless.

Critics argue that IPv4 redistribution perpetuates technical debt and delays inevitable IPv6 migration, creating a “zombie protocol” scenario where IPv4 limps along indefinitely while IPv6 never achieves critical mass. They point to security concerns: older IPv4 infrastructure lacks modern features like built-in IPSec, and maintaining dual-stack networks increases attack surface. Some also question market efficiency—speculators hoard addresses, driving prices artificially high and creating barriers for legitimate users in developing regions.

Definition: The criticism is that IPv4 redistribution creates a “zombie protocol” scenario where IPv4 persists indefinitely, delaying IPv6 adoption and fragmenting the internet. Critics point to security concerns (older IPv4 infrastructure lacks modern features) and market inefficiency (speculators hoard addresses, driving prices high).

Comparison: Unlike proactive IPv6 migration (which solves the problem long-term), redistribution is seen as a temporary fix that delays the inevitable. Unlike administrative allocation (which prioritizes need), market mechanisms allow speculation that can drive prices artificially high.

Application: However, the counter-argument ignores economic reality: IPv6 migration costs remain prohibitive for many organizations ($200,000-500,000 for typical enterprises according to 2025 industry benchmarks), and the 60% of internet traffic still on IPv4 means IPv4 connectivity isn’t optional—it’s mandatory for business operations. Redistribution provides a bridge period where companies can grow without massive capital expenditure, while IPv6 adoption naturally increases as hardware refreshes occur (typically every 3-5 years). Market mechanisms, while imperfect, allocate resources more efficiently than administrative rationing ever did—trading volume increased 340% between 2019 and 2024, demonstrating market efficiency. The alternative—forcing premature IPv6 migration—would bankrupt smaller ISPs (which often operate on thin margins) and limit internet growth in emerging markets (where IPv6 adoption remains below 20% as of late 2025). Redistribution isn’t perfect, but it’s the least-bad solution available—and as of early 2025, it’s the only solution that works at scale without massive economic disruption.

These criticisms hold merit in specific contexts. IPv6 does offer superior security architecture, and perpetual IPv4 reliance could fragment the internet. Speculation exists—some entities acquire blocks purely for resale, not use. And yes, redistribution doesn’t solve the fundamental 32-bit limitation; it merely delays the problem.

Best Practices for IPv4 Address Acquisition

Audit current utilization first—many discover 20-30% waste. Prioritize clean WHOIS records, contiguous addressing, and established marketplaces with escrow services. Budget 10-15% above market price for fees.

Companies seeking IPv4 blocks should first audit their current utilization—many discover 20-30% waste through subnet consolidation before purchasing new space (though consolidation requires network engineering time and may cause temporary service disruptions). When buying, prioritize blocks with clean WHOIS records (no historical abuse complaints—though abuse history can be difficult to verify completely), contiguous addressing (easier routing—contiguous blocks reduce BGP routes by up to 40% compared to fragmented blocks), and RIR transfer approval likelihood (established sellers with clean records have higher approval rates). Work with established marketplaces that provide escrow services and handle RIR paperwork, as DIY transfers risk rejection and delays (approximately 5-10% of DIY transfers face rejection according to 2025 data, versus <2% rejection rate for marketplace-facilitated transfers). Budget 10-15% above market price for transfer fees ($500-5,000), legal review ($2,000-10,000 for large transfers), and potential RIR appeals (though appeals are rare—<1% of transfers require them).

⚠️ Production Deployment Best Practice: Always audit current utilization before purchasing new IPv4 space—many organizations discover 20-30% waste through subnet consolidation. Work with established marketplaces that provide escrow services and handle RIR paperwork, as DIY transfers risk rejection (5-10% rejection rate) and delays. Budget 10-15% above market price for transfer fees, legal review, and potential RIR appeals.

Mini-Case: An ISP needed 8,192 addresses but only found fragmented /24 blocks available. Action: Used InterLIR Marketplace to locate a contiguous /19 block from a single seller. Result: Reduced BGP routes by 32 entries, improved routing convergence time by 40%, and simplified network management.

For sellers, prepare documentation proving legitimate ownership (RIR records, historical allocation documents) and clean usage history (no abuse complaints, no blacklist entries—though some sellers struggle to document usage history for addresses allocated decades ago). RIRs scrutinize large transfers (>/20 blocks) more heavily, so expect 60-90 day timelines (versus 30-45 days for smaller transfers), though actual timelines vary by RIR region and transfer complexity. Consider leasing as an intermediate step—it generates revenue (8-12% of purchase price annually) while retaining ownership for future needs or potential price appreciation (though prices have been relatively stable since 2022, with /24 blocks trading in the $6,000-8,700 range as of late 2025). Tax implications vary by jurisdiction; consult tax professionals, as IP address sales may qualify as capital gains (if held long-term) or ordinary income (if held short-term or by certain entity types) depending on holding period and entity structure (though tax treatment remains unclear in some jurisdictions, creating uncertainty for sellers).

The Future of IPv4 Address Space

IPv4 remains essential despite IPv6 growth. With 40% global IPv6 adoption and regional variations, companies serving global markets must maintain IPv4 connectivity indefinitely.

IPv4 will remain essential for the foreseeable future despite IPv6 growth (though “foreseeable” is subjective—some predict IPv4 remains essential for 10+ years, others suggest 5-7 years). As of late 2025, IPv6 adoption reached approximately 40% globally, but adoption varies dramatically by region—North America hovers around 50%, while many developing regions remain below 20% (creating a geographic asymmetry that forces global companies to maintain IPv4 support). This asymmetry means companies serving global markets must maintain IPv4 connectivity indefinitely (though “indefinitely” may mean 5-10 years, not forever). The secondary market will continue maturing, with prices stabilizing as supply (from organizations completing IPv6 migration—though migration rates remain slow, with only 5 percentage point growth globally between 2022-2024) meets demand (from growing companies and IoT deployments—IoT devices often require IPv4 due to legacy compatibility requirements).

Mini-Case: A global SaaS provider serving customers across 50+ countries needed to maintain IPv4 connectivity despite planning IPv6 migration. Action: Established a long-term IPv4 leasing strategy through InterLIR Marketplace, securing /20 blocks on 3-year leases across multiple RIR regions. Result: Maintained 100% global reach, avoided $500,000+ in IPv6 migration costs, and preserved capital for core product development—demonstrating how redistribution enables strategic IPv4 management alongside IPv6 planning.

Long-term, IPv4 may become a premium resource—scarce enough to command high prices but common enough to remain accessible. Some predict a “tiered internet” where IPv4 addresses become status symbols, similar to premium domain names. However, redistribution mechanisms ensure efficient allocation, preventing the hoarding scenarios critics fear. The great IPv4 redistribution isn’t a temporary fix—it’s the new normal for internet infrastructure economics.

Conclusion

IPv4 redistribution isn’t just a market mechanism—it’s the solution to a distribution problem masquerading as scarcity. With over 1.3 billion dormant addresses worldwide, the “shortage” reflects inefficient 1990s allocation, not actual scarcity. Redistribution matches supply with demand without infrastructure overhauls, providing a bridge period for companies to grow while IPv6 adoption naturally increases.

Definition: IPv4 redistribution is the market-driven solution to address misallocation, transferring 1.3-1.4 billion dormant addresses from holders who don’t need them to organizations that do, typically completing in 30-90 days through RIR-approved transfers.

Comparison: Unlike administrative allocation (which created the distribution problem through inefficient 1990s policies) or forced IPv6 migration (which costs $200,000-500,000 per enterprise), redistribution leverages existing infrastructure and market mechanisms to solve the problem without massive capital expenditure.

Application: The technical requirements are clear: RIR transfer processes, marketplace facilitation, and proper due diligence. The business value is quantifiable: predictable costs ($18-34 per address as of late 2025), avoided migration expenses ($200,000-500,000), and revenue generation for holders ($7,000-10,200/year for a /20 block if leased). And the decision framework is straightforward: audit utilization, prioritize clean records and contiguous addressing, work with established marketplaces like InterLIR, and budget for fees.

Mini-Case: A mid-size enterprise needed IPv4 expansion but faced budget constraints. Action: Partnered with InterLIR Marketplace to lease a /20 block instead of purchasing, paying €1,888-2,080 monthly. Result: Gained immediate address access without capital expenditure, maintained operational flexibility, and deferred purchase decision until budget approval—demonstrating how redistribution provides multiple pathways to IPv4 access.

The great IPv4 redistribution isn’t a temporary fix—it’s the new normal for internet infrastructure economics. Companies that understand this reality can access the addresses they need, monetize unused assets, and position themselves for success in an increasingly connected world.

Frequently Asked Questions

Is there really an IPv4 address shortage?

+

No. Over 30% of IPv4 addresses are completely unused, and another 30% exist in pseudo-used states. The ‘shortage’ reflects inefficient allocation, not actual scarcity. Approximately 1.3-1.4 billion addresses remain dormant worldwide, with 40 million unused addresses in Germany alone.

How much do IPv4 addresses cost?

+

As of late 2025, IPv4 addresses trade for $18-34 per address on average. A /24 block (256 addresses) costs $6,000-8,700, while a /20 block (4,096 addresses) ranges from $70,000-102,400. Larger blocks command premium pricing due to routing efficiency, with /18 blocks (16,384 addresses) trading for $250,000-350,000.

Why not just migrate to IPv6 instead of buying IPv4?

+

IPv6 migration costs $200,000-500,000 for typical enterprises and requires replacing incompatible hardware, retraining staff, and maintaining dual-stack infrastructure. With 60% of internet traffic still on IPv4, companies need IPv4 connectivity regardless of IPv6 adoption. Redistribution extends existing infrastructure lifespan.

How long does an IPv4 address transfer take?

+

IPv4 transfers typically complete in 30-90 days. The process involves seller initiation through their Regional Internet Registry (RIR), buyer justification of legitimate need, RIR approval, and WHOIS record updates. Larger transfers (>/20 blocks) face more scrutiny and may take longer.

Can I lease IPv4 addresses instead of buying?

+

Yes. Leasing options exist for companies needing temporary address space, typically priced at 8-12% of purchase price annually. Leasing generates revenue for holders while providing flexibility for lessees who may not need addresses long-term.

What happens to unused IPv4 addresses?

+

Unused IPv4 addresses represent stranded assets generating zero return. Organizations can monetize them through sale or leasing via marketplaces like InterLIR. A /20 block worth $70,000-102,400 generates $7,000-10,200/year if leased at 10% annually, turning dormant assets into revenue streams.

What is an IPv4 address?

Posted on by admin

An Internet Protocol (IP) address, particularly an IPv4 network address, serves as a unique identifier enabling devices to communicate over the internet. This IPv4 address, part of an elaborate IPv4 addressing scheme, ensures data reaches its correct destination. For instance, an IPv4 address example like 192.168.1.1 demonstrates the structure defined by the IPv4 address scheme, which is pivotal for internet connectivity.

The question of “What is the IPv4?” pertains to understanding this critical component of internet architecture. Simply put, an IPv4 address is a 32-bit numerical label assigned to each device on a network, allowing for inter-device communication. As we delve deeper into “What is the IPv4 address”, it becomes clear that the design and allocation of these addresses are meticulously planned to optimize network efficiency and scalability.

The development of the IPv4 address scheme was a groundbreaking step in digital communication, yet the IPv4 addressing scheme faces significant challenges, notably IPv4 running out. This limitation, inherent in the finite nature of the IPv4 space, underscores the urgent need for migration to IPv6, which promises an almost limitless number of addresses.

IP addresses come in two main types: IPv4 and IPv6. ISPs typically offer both versions, and the choice depends on specific needs. IP addresses are hierarchical and divided into four or six parts called octets. Each section represents different information and plays a role in IP address allocation managed through routing protocols.

To ensure successful data transmission, internetworking protocols facilitate communication between IP networks. The process depends on network connectivity. Subnetting is used to divide networks into smaller subnetworks, optimizing IP address usage.

Overall, IP addresses are essential for Internet communication, and understanding their fundamentals is valuable for individuals working with computer networks and web programming.

What is subnet?

A subnet, also known as a subnetwork, is a logical division of an IP network. Subnetting refers to the practice of splitting a network into multiple smaller networks. In the case of IPv4, a network can be identified by its subnet mask, which is a bitmask applied to an IP address using a bitwise and operation to determine the routing prefix.

For instance, consider the prefix 190.21.100.0/24, which has a subnet mask of 255.255.255.0. Subnet masks are typically represented in dot-decimal notation. Another example is 190.21.100.0/21, where 21 bits are allocated for the network prefix and the remaining 11 bits are reserved for host addressing in the IPv4 network.

When the routing prefixes of the source and destination addresses differ, traffic is routed between subnetworks through routers. Subnetting can improve routing efficiency and provide network management advantages, particularly when different entities within a larger organization have administrative control over specific subnetworks.

Subnets can be logically organized in a hierarchical architecture, enabling the partitioning of an organization’s network address space into a structured routing system.

IPV4 vs. IPV6 Explained

IPv4 is the current protocol used for connecting to websites and servers, but it faces several challenges. One major issue is the depletion of available IPv4 addresses. An IP address is a numerical label assigned to devices to access network content. Due to the limited number of IPv4 addresses, we are running out of them. Fortunately, IPv6 offers a solution by providing a significantly larger pool of addresses, with the capacity to accommodate 2128 unique addresses for each individual on Earth.

What’s the difference between an IPv4 and IPv6?

IP, short for Internet Protocol, refers to a device’s specific location on a network. However, it can be confusing because there are two types of IP addresses: IPv4 and IPv6. IPv4 was created in 1981 and is commonly used for devices connected to home routers or office computer systems. On the other hand, IPv6 has been implemented more recently.

IPv4 notation

Despite their differences, both IPv4 and IPv6 are categorized as IP addresses. The main distinction between them is their size, with IPv4 being 32 bits long and IPv6 being 128 bits long. However, for consumers, the practical significance of this size difference is minimal. IP addresses typically appear as strings of numbers separated by dots. Nowadays, most computers support both IPv4 and IPv6 protocols, so the choice of which type to use when browsing online is often inconsequential.

What is the IPv4 address structure

An IPv4 address in a computer network is a series of four numbers separated by dots. Each number can range from 0 to 255, representing a unique identifier for a device on the network. For instance, if we have an IPv4 address like 212.168.0.0, the first number is 212, the second is 168, the third is 0, and the fourth is 255.

IPv4 and ipv6 notation

What is the IPv6 address structure

IPv6 is the latest version of the Internet Protocol and is designed to replace the current IPv4 protocol. It serves as a network layer protocol for transmitting data packets across multiple IP networks. IPv6 was developed to address the limitations and increasing demand for IP addresses in IPv4. Unlike IPv4, which uses 32-bit addresses, IPv6 utilizes a hierarchical structure with 128-bit addresses. Each bit in an IPv6 address represents a number from 0 to 256, and the address is divided into eight groups of four hexadecimal digits separated by colons. The implementation of IPv6 involves two layers: addressing, which determines the destination of packets, and routing, which determines the path for packet delivery. Every device connected to an IP network must have one or more unique IPv6 addresses associated with it.

Why we run out of IPv4

IPv4 has a unique addressing system where each device connected to a network is assigned an individual IP address. However, the limitation of IPv4 is that it can only accommodate approximately 4.3 billion devices on a single network.

This limitation means that IPv4 addresses are running out, and Internet Service Providers (ISPs) are already facing shortages when providing IPv4 addresses to new customers. Consequently, there is a need to replace IPv4 with an alternative addressing scheme like IPv6 to overcome these limitations and ensure the availability of addresses for future devices.

Who needs to buy IPv4 and IPv6 addresses

Even if you do not own your IP address, you can still obtain one from specialized companies that sell them. Similar to how businesses ensure their physical locations are easily located on a map, they also want their IP addresses to be clearly communicated. Companies purchase large blocks of IPv4 addresses to allocate them among their branches and other sites, making it convenient for customers and potential partners to find them online. By assigning a unique IP number to each site, businesses ensure that their headquarters has a recognizable IP address readily available for visitors seeking their online information. Many different types of companies require a significant number of IPv4 and IPv6 addresses, including internet service providers, hosting companies, cloud services, VPN services, various internet businesses, and banking/payment services.

There a lot of different companies which need to buy a lot of IPv4 and IPv6 addresses:

  1. Internet service providers;
  2. Hosting Companies;
  3. Cloud Services;
  4. VPN services;
  5. Various Internet Businesses;
  6. Banking and payment services.

LIR and RIR

The majority of IP addresses are owned by Local Internet Registries (LIRs), which obtain IP space from Regional Internet Registries (RIRs) in blocks for private use within specific geographic regions. Each RIR is responsible for managing the availability of IP space, registering accounts for assignment within those spaces, and determining the allocation of IP blocks. The five RIRs are as follows:

Each RIR covers specific geographical regions and plays a vital role in the allocation and
management of IP addresses within their respective territories.

  1. ARIN (American Registry for Internet Numbers): Administers IP addressing space within North America.
  2. RIPE NCC (Réseaux IP Européens Network Coordination Centre): Responsible for IP addressing space administration in Europe and Africa.
  3. APNIC (Asia-Pacific Network Information Centre): Manages IP addressing space within the Asia-Pacific region.
  4. LACNIC (Latin American and Caribbean Network Information Centre): Administers IP addressing space in Latin America and the Caribbean.
  5. AFRINIC (African Network Information Centre): Responsible for IP addressing space administration in Africa.
