Every IPv4 packet starts with the IPv4 header, a fixed-size data structure. Networking hardware uses it to route the packet to its destination because it contains a range of crucial data. The fields in the IPv4 header are listed below in the following order:

• Version (4 bits) – This field indicates the version of the IP protocol being used. This parameter is always set to 4 for IPv4 packets.
• Header Length (4 bits) – This parameter indicates the length of the header in 32-bit words. This number might be anywhere between 5 and 15, as the header may have optional fields.
• The Type of Service (8-bit) field is used to describe any unique handling needs as well as the packet’s priority.
• Total Length (16 bits) – This field indicates the overall length of the packet in bytes, including the header and data.
• Identification (16 bits) – This field is utilized for fragmentation and reassembly. Each packet is given a special identification number that can be used to put together broken packets.
• Flags (3 bits) – These bits are used to regulate fragmentation. The “More Fragments” (MF) flag is set in all fragments save the final one, while the “Don’t Fragment” (DF) flag specifies that the packet shouldn’t be fragmented.
• Fragment Offset (13 bits) – This field indicates the offset of the data in the packet, relative to the beginning of the original unfragmented packet.
• The maximum number of hops a packet is permitted to make before being deleted is specified in the Time to Live (8-bit) field.
• Protocol (8 bits) – This field identifies the protocol used in the data section of the packet, such as TCP, UDP, or ICMP.

• Header Checksum (16 bits) – This field is used to check the integrity of the header.
• The IP address of the sender is contained in the Source Address (32 bits) column.
• The IP address of the recipient is contained in the destination address (32 bits) field.
• Options (variable) – This field is optional and can be used to include additional information, such as security and routing information.

The IPv4 header format has now been briefly explained.

Introduction

A subnet mask is a critical component in computer networking that defines the boundaries of a network. It is a numeric code that tells network devices which part of an IP address is used to identify the network and which part is used to identify the individual device. In simpler terms, the subnet mask is used to separate an IP address into two parts: the network address and the host address.

In this article, we will delve deeper into what a subnet mask is, how it works, and why it is essential in computer networking.

What is a subnet mask?

A subnet mask is a 32-bit code that is used to separate an IP address (check https://interlir.com/blog/2022/04/06/what-is-an-ipv4-address/) into two parts, namely the network address and the host address. The network address is used to identify the network, while the host address is used to identify the individual device within the network.

How does a subnet mask work?

A subnet mask works by determining which part of an IP address is used to identify the network and which part is used to identify the host. The subnet mask does this by using a binary code that is applied to the IP address. The binary code has a series of 1’s and 0’s that determine which part of the IP address is used to identify the network and which part is used to identify the host.

Types of subnet masks

There are two types of subnet masks: classful and classless . Classful subnet masks are used in traditional networking and are based on the IP address classes, whereas classless subnet masks are used in modern networking and are based on the variable-length subnet masking (VLSM) technique.

How to calculate a subnet mask

To calculate a subnet mask, you need to know the number of bits used to identify the network and the number of bits used to identify the host. The number of bits used to identify the network is determined by the subnet mask. The number of bits used to identify the host is the remaining bits of the IP address.

Subnetting and subnet masks

Subnetting is the process of dividing a network into smaller subnetworks. Subnet masks are used to determine the boundaries of these subnetworks. Subnetting is essential in computer networking as it enables network administrators to manage network traffic more efficiently and provides additional security measures.

Why are subnet masks important?

Subnet masks are important because they determine the boundaries of a network. By defining these boundaries, network administrators can manage network traffic more efficiently and provide additional security measures. Subnet masks are also used to divide a network into smaller subnetworks, which allows for more efficient use of network resources.

FAQ

Q: What is CIDR notation?

A: CIDR notation is a compact way of representing an IP address and subnet mask in a single notation. It uses a slash (/) followed by a number to represent the number of bits used to identify the network. For example, 192.168.0.0/24 represents an IP address of 192.168.0.0 with a subnet mask of 255.255.255.0.

Q: How to use CIDR notation?

A: CIDR notation is used to simplify the representation of IP addresses and subnet masks. It is commonly used in networking to configure network devices and to represent IP address ranges.

Q: What is the difference between a subnet mask and a default gateway?

A: A subnet mask and a default gateway are both used in networking, but they serve different purposes. A subnet mask is used to define the boundaries of a network, while a default gateway is used to direct traffic from one network to another.

Q: How to find the subnet mask of a network?

A: To find the subnet mask of a network, you can use the ipconfig command in Windows or the ifconfig command in Linux or macOS. You can also check the configuration of your router or network device to find the subnet mask.

Q: How to change the subnet mask of a network?

A: To change the subnet mask of a network, you will need to access the configuration settings of your router or network device. From there, you can change the subnet mask to the desired value.

Q: What is a broadcast address?

A: A broadcast address is a special IP address that is used to send a message to all devices on a network. It is typically the last address in a network and is represented by setting all host bits to 1 in the subnet mask.

Q: What is the maximum number of hosts per subnet?

A: The maximum number of hosts per subnet is determined by the number of host bits in the subnet mask. The formula for calculating the maximum number of hosts is 2^n – 2, where n is the number of host bits in the subnet mask.

Q: How to calculate the number of subnets in a network?

A: To calculate the number of subnets in a network, you need to know the number of bits used to identify the subnets in the subnet mask. The formula for calculating the number of subnets is 2^n, where n is the number of subnet bits in the subnet mask.

Conclusion:

In conclusion, subnet masks are a critical component in computer networking that define the boundaries of a network. They are used to separate an IP address into two parts, the network address and the host address, and are essential in subnetting, managing network traffic, and providing additional security measures.

3. How IP Blocklists Work

IP blocklists function by preventing communication between an organization’s network and potentially harmful IP addresses. Here is a step-by-step explanation of how IP blocklists work:

1. A blocklist is implemented in the organization’s security infrastructure, such as firewalls, intrusion prevention systems (IPS), or security gateways.
2. When an incoming request or connection attempt is made, the security system checks the originating IP address against the blocklist.
3. If the IP address is found in the blocklist, the connection is denied, and the attempt is logged for future analysis.
4. If the IP address is not listed, the connection proceeds to the next stage of the security process.

4. Advantages of Using IP Blocklists

IP blocklists offer several benefits, including:

Enhanced Network Security

By blocking known malicious IP addresses, blocklists significantly reduce the risk of cyber threats, such as DDoS attacks, malware, and phishing.

Reduced Spam

Blocking IP addresses associated with spam helps in minimizing unwanted emails and maintaining a cleaner inbox

Improved Network Performance

Blocking unwanted traffic from malicious IP addresses can lead to better network performance by freeing up bandwidth and reducing unnecessary load on network resources.

Proactive Defense Mechanism

IP blocklists provide a proactive defense against cyber threats by preventing communication with known malicious sources, rather than relying on reactive measures after an attack has occurred.

Experts and target audiences noticed an unusual turn in pricing for IPv4 addresses. For the last few years, addresses for blocks less than (up to/17) were more expensive than large ones (starting from /16). From the middle of 2020 til August 2021, the pricing gap was ranging widely (2,4% – 17,5%). Many sellers started breaking huge blocks to increase their income.

In 2022 the situation turned vice versa. Huge blocks raised in price. Until May this trend was stable. As the large blocks became costly, smaller blocks became cheaper. The tendency of the previous year caused the general pricing diversity. From 1,1% (end of 2021) to 7,5% (April 2022).

To stay at a competitive level, it’s important to monitor the pricing trends in 2023 24/7. It will help to correct the strategy and meet the market terms. For example, a customer may think about the profit of purchasing four /18 cheaper or one /16. The last is more convenient, the deal will be held quicker. The transfer fee will be charged only once.

If a seller has /16 but uses only its small part (for example, a/20) comes a question: what is it better to sell? The entire block or its passive space? Is it better to divide the address into smaller parts?

The smart strategy depends on the current market situation. Regular changes need regular analysis.

Every belonging or something we control can be called property. For example, real estate objects or land we can call regular property. There are also intangible properties (names of brands, logos, unique content, etc.). This category is rather complicated.

Management or ownership of intangible objects differs from those of physical assets. Thus, internet numbers or names can be provided on contract terms for a certain period of time or without time limits. A contracting party can proceed with a registration procedure – to become a member.

The Internet Assigned Numbers Authority (IANA) is the main online registry. It heads all the other registers with web protocols, numbers, and names. For example, online traffic is working on HTTP protocol. In its turn, those protocols are using ports. No other protocol can work on the registered port. So, registration is an important condition. Lists with all the protocols are published on IANA. There one can find updated information.

Each register is managed. Managers have to cover the spending. That’s why registration is paid. Users pay for numerous network resources, including IPs, names, etc.

Presently, there exist five registries functioning on a regional level for Number Resources. They charge customers different fees.

Roots Of System Development

When the internet was an innovation, its initial organization DARPA signed a contract with the Information Sciences Institute at the University of California. They covered IANA’s responsibilities. They made the list of identifications according to web locations (interfaces). These numbers are known as IP addresses. Technical progress required particular changes.

The internet was actively developing. From 1992, commercial traffic moved online. It was in 1992. The result of such policy change turned into appearing in two directions. On the one hand, networks worldwide started using internet connections. On another hand, the American government tried to avoid spending on supporting the centralized base of domains and IPs. The government started activities to turn internet administrative needs into a private sector. At the end of 1992, RFC 1446 offered an initiative to divide the registration for serving global users more diversely.

The cooperation of network operators was aimed at changing the principles of Internet Number of Resources. The registry had to become more regionalized. In Europe, the RIPE NCC appeared (in April 1992). APNIC (Asia-Pacific region) started its way in 1993.

In the USA the initial step for privatization was the creation of the American registry for internet numbers ARIN (1997).

Today there are five existing Regional Internet Registries. RIRs’ function is to run IP registrations. In several regions, National Registries (NIRs) work to support RIRs.

NIRs are operating under the supervision of RIRs. The difference is that they first serve customers in a certain country. In such a way, operators can communicate in the language they prefer, work under the law on the local level, and use the local currency.

What’s Paid?

Fee terms and schedule is individual for each RIR/NIR. Customers are charged for three basic aspects:

• a membership charge that provides the right to register IP, and participate in voting;
• a non-member fee to use a registry IP function for an organization;
• a transaction charge for all kinds of transfers.

Most organizations are only charged as membership registrants or non-membership customers.

As a member, an organization can implement RIR management activities by voting. Those organizations that want to achieve smooth functioning, are taking serious responsibility. There are some restrictions for some organizations that don’t allow them to take a membership with other companies. There are also those who don’t want to lead management.

Setting Fees by RIR

RIR members choose a board on elections. The board suggests and sets the charge schedule once a year. Some regional RIRs are allowed to set fees by themselves. According to standard procedure, the board is the one to offer an idea. The final decision is taken after voting.

Setting IP fees can seem a boring task for some people.

Any changes concerning fees (sizes, ways) become the center of webspace attention immediately.

Prices

In the following guide, we’ll demonstrate the charge of the RIRs in 2023. The information concerns 65,000 IPv4 addresses (a class B).

Different RIRs have different fees. It concerns both the size and the schedule. Moreover, the difference can be huge. For example, NCC RIPE canceled the differentiated charge. Instead, they set low commission that is compulsory for everyone. APINIC sets base charge. Extra fees or discounts depending on the IP space and the location of the organization.

The fees are reviewed once a year. In 2023 payments will rise.

AFRINIC

There are seven levels of fees for members and the same quantity of levels for the number of resources under its management. Costs vary from $3,150 to $48,400.

For non-members, the fees are $200-2,500 per year.

According to Afrinic’s policy, transfers are available only on emerging and acquisition terms.

APNIC

It sets the charge for base membership – at 1,180 AUD. Further payments depend on the amount of IP space that belongs to the registrant. Payment is reduced twice for the poorest countries.

The minimal annual charge is 1,180 AUD. Price for A/16 (Class B) is 9,626 AUD.

To sign-up, you have to pay 500 AUD.

Transfers are paid 20% of the membership charge per year.

ARIN

In 2022, the company set a fee limit for legacy resource owners to $150. The plan was to raise the sum by $25 each year. There are eleven levels of charge for registered organizations assigned to the plan. Transfers cost $500.

LACNIC

23 charge levels for partners with membership. Payment is from $600 to $365,000. The first-time assignment may cost $2,500 or $5,000. It depends on the size. After that, there is a fixed cost per year – of $600.

Special offer – discounted fees paying for 30 days. Transfers are available with zero commission.

RIPE NCC

All the customers make payments on the same terms. In the previous year, the first-time registration cost 1,000 euros. Fees per year are 1,400 euros.

Transfers are free. Extra cash is divided between members.

The network IP addresses vary from each other so network operators require expert guidelines. Daily, each of us gets suspicious letters on the email address that’s why the reputation of the sender is of high importance. In practice, senders’ identification on the basis of personal IP is a real challenge, and quite useless.

For years, the heads of email web systems ignored incoming correspondence sent from home internet IPs. By the end of 2021, the number of wired home network connections reached more than 1 million. Maintaining a database of reliable email users would be difficult. The main issue could be concerned with the differentiation between those numerous bots sending viral content or leading suspicious activities.

Thus, dedicated systems for email sending should be used. The duty of system administrators is to evaluate the reputation of those systems that are less numerous. There are various tools for such analysis.

Some indicators of IP address reputation are measured similarly.

It’s necessary to find out the following:

1. Should the income mail come from this address?
2. What’s the geo?
3. Is there a malware infection on an IP?
4. Is it using network users’ personal data without permission?

The Importance Of the Reputation for the IP

Setting IPs in accordance with equipment for their functioning on the webspace is only a part of the job. It’s not less essential to create a new spatial range of IP addresses.

Any remarkably wide range of IPs previously was used on another network. Despite the Regional or National Internet Registry will make a transfer to your company visible, those changes aren’t shown up immediately and automatically in most of the tracking tools. Thus, it’s necessary to update those systems so that they provide actual information concerning management, geographical location, and purpose.

The Scoring Algorithm for IP Reputation

To create a friendly reputation, it’s better to avoid sudden switching between users. An accurate and well-planned deployment will bring much better results. Using address space right before the transfer is risky – it may be spoiled. Leave it for some time, so it won’t join the blacklist. If your purpose will be the same that the previous user had, you’ll have to examine the databases on this subject.

Reputation is being tracked for IPs that are sending emails. This point should still be considered. To be aware of the current situation, one may join the Mailop community. In the best practical cases, host mailing data, lists, and discussions can be rather useful.

If you’re transferring IPs from another geography, and it will be available for consumer web clients, contact the company managing geodata for IP addresses (GeoIP). Consumer content can have a particular specification according to the market. It can be licensed. The managing companies are keeping the data access settings according to local or owner restrictions.

If the IP was used in a region with not the same language as yours, you may take advantage of the platforms describing the transfer. You can set the interface with any language you choose or that is the best for the target audience.

If you have another purpose for using the address than a former user, you need to ensure that the channels that work with reputation contain updated information.

If you have another purpose for using the address than a former user, you need to ensure that the channels that work with reputation contain updated information. Then you won’t be recognized as a suspicious user and your network won’t appear in the block list. For example, IPs that were used for network access by subscribers before can be repurposed for cloud server means. For sending trusted correspondence, you need to remove the IP from various lists and databases. If the address isn’t meant to send emails, it will definitely be blocked.

Reputation Monitoring Tools

Databases with Geo IP are available on Brothers WISP. This resource can be useful to the consumer addresses in case the regional services restrict the content distribution. For example, gaming sites or resources with video content.

The lists of recommended networks are led by the project called Spamhous. On their basis, it’s easier to evaluate the traffic quality.

The Cleanup Procedure

Check the reputation of the new IP range at influential sources. Update if required. It’s necessary to find out the lists considering the aim to reach. To change the outdated information about the registrant, you should contact the administration team. Let them know about any change – geo, purpose, etc.

The procedure is time taking. It’s better to put time into your deployment planning. Some teams prefer to solve the issues as they come.

IPv4 addresses are a limited resource that may run out sooner than you think! Leasing IPv4 addresses can ensure your business has the IP space it needs when leasing IPv4 addresses in 2023. If you wait until the last minute, your business could be left behind, so start planning now! This guide will help you understand what IPv4 addresses are and how they work and how to lease them.

Why should you lease IPv4?

You may want to lease your IPv4 addresses if you don’t need all of them at once or ever. For example, leasing makes sense if you’re running a small business and don’t have many employees but need more than one public IP address. An Internet Protocol version 4 (IPv4) address is a numerical label assigned to each device that connects to a computer network that uses IP. The numbering system uses four numbers separated by periods (also called an IP address) and is expressed in dotted-decimal notation, such as 192.168.2.1.

Some numbers are reserved for a particular use, so they can’t be used leased or purchased from a service provider. Typically these are low-numbered addresses with special meanings, including 0 and 255, although it varies depending on country regulations.

How much will leasing cost?

 This year, even that pool has been drained with only millions of addresses available for allocation. RIRs will hand out the remaining IP addresses in chunks of 256. By 2023 we’ll have run out, and there won’t be any more freely available addresses unless some alternative protocol or system is adopted or created, for example, IPv6.

 The problem is that not everyone wants to use IPv4 addresses and is searching for an alternative. There are some intriguing ideas for alternative protocols (see Web 3.0). Still, it will be years before any of those can come into play, so getting your hands on an IP address from a network provider will be necessary. The good news is that you can acquire these well ahead of time. The bad news is there’s no guarantee that you’ll ever actually need them. It all depends on how fast other alternatives come into play and how many devices you own.

 There are a few ways to lease an IP address from a network provider. For example, Google offers IP addresses that are leased as cloud services. Google Cloud Interconnect provides customers with public IP addresses on three continents and options for private interconnects between data centers that ensure performance and security. That is just one of many alternatives to acquiring your blocks of IP addresses when they become available through providers like T-Mobile and Interlir.

Why would anyone lease unused IP addresses?

It depends on how much space you need.

The Internet Protocol is one of many protocols (series of rules) that govern the communication between a computer and a network. The Internet Protocol defines an IP address as a unique string of numbers that can be used to identify any device on an IP network. For example, your computer has an individual IP address that allows it to connect with web services you’ve requested or video chat with friends. But it turns out we are running out of those addresses, and soon there won’t be enough for everyone’s devices. So, here’s how you lease IPv4 addresses ahead of time, so they’ll be ready when you need them.

If you’re not using your IP addresses, why not lease them out to businesses that need additional addresses? In addition to increasing your profits on unused assets, leases generate recurring income every month. You can buy and lease your unused IP addresses from anywhere in the world: Germany, USA, Africa. To do this, you need to create a sub-allocation pool of one or more contiguous /8s (256 to 65,536 individual /24 blocks). The person leasing an address from you will pay for a single allocation from that pool, which is how they receive their desired number of IP addresses. When leases expire after five years (or earlier if either party decides), you’ll be able to use those blocks again for your purposes. This way, everyone wins! You can lease unneeded IP addresses and create a stream of recurring revenue; potential lessees get access to address space without waiting for a future round of IPv4 allocations; Internet users have uninterrupted access when transitioning from one leased block to another.

 Some might worry that allowing organizations to lease unused addresses will take away Internet users’ IP address space. Still, leases typically last five years, after which organizations will receive a single allocation from your pool and have their leased blocks returned to you. So there’s no long-term impact on future IP allocations. If anything, leases are an incentive for ISPs and businesses with large stockpiles of unused addresses to release them back into circulation rather than hoard them. This additional availability of IPv4 addressing space should keep IP address assignment needs—and costs—from escalating for many years. In other words, getting creative about allocating or renting out your IP addresses can generate extra revenue without affecting Internet users’ ability to get online.

 So why would anyone lease unused IP addresses? In many cases, there’s no downside. You don’t lose control of your unneeded IP addresses since you’ll receive back all of them plus a single allocation from your pool after five years (or sooner if either party decides). Plus, you can generate recurring revenue every month without selling or transferring your existing address space. It’s a win-win for everyone involved! If you’d like more information about leasing IPv4 addresses and setting up an allocation from one or more contiguous /16s—or if you need assistance setting-up a sub-allocation pool in RIPE DB—don’t hesitate to get in touch with Interlir. We’re here to help!

 Contact us if you’re interested in leasing your unused IP addresses and don’t know where to start. We can provide more information about how sub-allocation pools work, answer any questions you may have, and give you assistance getting started. And remember: You don’t need to use RIPE DB for a sub-allocation pool; if you prefer using legacy RIPE tools instead, we can set that up for you. Suppose you’re new to leasing IP addresses or entering into such agreements. In that case, we also offer a  training session that covers all aspects of managing leasing space and what happens when leases expire.

Who are some of the organizations leasing IP address space?

Germany, China, and India have all been leasing (renting) IP address space to ISPs since 2010. An emerging industry of providers rents small or large blocks of IP addresses every month. This short-term rental option lets you cover your immediate needs without a long-term commitment—ideal for organizations that might not need more than 1-2 blocks of space in any given year. Rental prices vary depending on the provider and the time/size of the block required.

IPv4 Provider is a company that leases out IP addresses. They have become more popular as organizations realize they can cover their short-term needs without a long-term commitment. In addition, you can rent/buy an ipv4 block cheaper; some providers offer discounts for renting multiple blocks of IP addresses. For example, if you lease two blocks of 1024 IP addresses each, you might get a 3% discount on your total price. This can make leasing an attractive option for smaller organizations with more immediate needs but who don’t want to commit to a long-term contract or pay higher prices for permanent IP address space. The provider typically handles all maintenance and technical support related to your leased IP address space, so there’s no need for you to set up or maintain your equipment.

What advantages does leasing provide?

If you’ve found a block of IP addresses, you’d like to rent or lease, it’s time to start inquiring about pricing and rates. The prices can change often based on availability and location but increased 100% since 2021 to 50$ per IP. These services offer savings, but they’ll also allow you to save space by bundling multiple IP address ranges into one lease. For example, if your company is looking for a /16 (that’s 65,536 unique IP addresses), you could quickly be paying millions USD when purchasing that many IPs outright—and then still have a lot of unused IP space.

 Renting IP addresses isn’t just beneficial for businesses and government entities who need space but don’t want to commit to long-term leases. Even homeowners are turning to IP address leasing and rental services as Internet connections become increasingly vital—and often nearly necessary—too many facets of life today. A typical home may require a static public IP address for its primary connection and more ephemeral (often dynamic) IP addresses for wireless routers and home networks. No matter your needs, you can lease an IP address with any provider from all over Europe and other regions worldwide.

Is there an alternative solution?

Many ISPs, organizations, and other entities that currently get IP addresses from organizations like ARIN or RIPE will be interested in leasing IPv4 addresses when they become available for lease. New networks are also likely to emerge internationally—primarily in Germany, which has already begun preparing a leasing market; time will tell whether both organizations and individuals embrace it outside of Germany. If you’re planning on launching a new network and want to quickly gain access to a large block of IP addresses (for instance, if you’re a data center company), then your best bet is probably going to be renting them on an international level.

 From a cost perspective, leasing IP addresses is often cheaper than buying a large block of static IP addresses. Organizations that rely on public Internet backbones for their business operations may also gain access to new address blocks through service providers and regional network operators. Most importantly, moving away from static leases towards dynamic pooling may also help ensure that we don’t run out of IPv4 addresses in five years! When you lease an address, it becomes part of a pool that your ISP or provider can assign to different devices at different times, preventing anyone particular device from consuming too many individual IP addresses. ISPs could even use lease pools for everyday Internet users – if you rent a static IP address today, you probably have hundreds of unused addresses. 

 Your best option for accessing a large pool of IP addresses for both new and established networks will be renting addresses from an existing network operator. As mentioned above, Germany has already built up a significant market for leasing IPv4 addresses; operators are now using some unused address blocks to lease out to other organizations. It’s likely that Germany, and potentially other countries, will create more leasing markets as more and more IP addresses become available. But whether or not your country makes an IPv4 address-leasing market, you’ll have no trouble accessing them internationally – many ISPs already offer leased address blocks. In contrast, major national providers like Comcast, Deutsche Telekom, NTT Communications, and Singtel have all said they will rent out different IP addresses.
