Buy IPv4 Networks

It’s all too clear how quickly IPv4 addresses are being exhausted, and while there has been a transition in motion, bridging the gap will require an immediate purchase of IPv4. So how to buy IPv4? Many people find themselves caught up with other business needs, but this transition can’t be done overnight – it takes time and dedication. And when things seem out of hand or frustrating? It might not matter what they were before because it is irreversible once this transition starts in motion. This means that now is the perfect time to invest in getting those elusive IPs! All you have to do is come visit us at Interlir Marketplace for quick services and great deals based on years of experience, insight, knowledge, and rules and regulations, making this transition much easier for everyone involved!

IPv4 is running out. If your company hasn’t already started transitioning to IPv6, they will soon find themselves unable to reach their full potential. A lack of extra IPv4 address space will slow down productivity because IPv6 has exponentially more address space available for devices and networks than its predecessor. Business owners need to buy IPv4 addresses before the prices go up or become obsolete; otherwise, it could take a lot of time, money, and patience to acquire one manually. You don’t want that kind of headache when you can work with experienced experts handling this transaction, so they’re done fast and at an affordable price? Just talk to us!

Do you want to find out why Interlir Marketplace is perfect for purchasing an IPv4 address?

Buyers – when it comes to buying IPv4 addresses, rely on us to negotiate on your behalf while taking care of all those tedious administrative tasks.
Sellers – when you want to sell your IPv4 blocks or other resources online, let us do the heavy lifting so that you can focus on what really matters: generating revenue for yourself.

When it comes to purchasing IPv4 address space, it takes diligence and planning. Acquiring this fundamental property also takes quite some time since many different stakeholders are involved – none who are willing to budge anytime soon without something in return. Of course, if you try to rush through this painstaking process, things can only get worse: no matter how much you plan ahead, there’s always a possibility that an unforeseen turn of events will lead you back to square one again. And so, before starting your search for available IPv4 blocks/addresses, make sure you’re prepared by knowing exactly what type of IPv4 block or address range you’re looking for (i.e.,/24 subnet mask) and what price are they going for today (from 45 euro).

To purchase IPv4 address space, one must take pragmatic measures. This ranges from getting ready to sell or trade your unused IPv4 address when the opportunity arises to learn how to find an IP block or IP address range that suits what you’re looking for so they can reach out accordingly and set up a deal. Regardless of who you are or what kind of need you may have, we’re here to make sure that if buying an IPv4 is what you want, it will happen smoothly and without hiccups because, after all, our name means The right thing done right.

While it might seem daunting to buy IPv4 addresses, if you understand what’s required, the whole process will be much simpler. Ensure that you’re patient with buying through this complex process and know when suitable opportunities arise for a specific block of IPs to move forward quickly and successfully. A nuanced approach to marketing allows us to provide a client-oriented service throughout every step in their journey, guiding them based on their needs but still adapting appropriately. Hence, nothing about this process becomes unclear to them. With our expertise readily available, what better way than now to venture into the market without all these headaches?

Customer satisfaction is our number one priority. For over a decade, we’ve specialized in doing just that: satisfying clientele needs around the world! From offering recommendations on obtaining IPv4 addresses at bargain prices to assisting with designing clever marketing campaigns, self-educating ourselves, and observing first-hand experience – it’s all been leading up to this.

We do it all, even buy IPv4.

Have you considered buying IP addresses for your company yet? Don’t hesitate to reach out to us if you need guidance along the way. Our experts can answer any of your questions and guide you in picking the best package for your needs. Our streamlined and straightforward process means less time and money wasted- because who doesn’t want that? Get all the facts before proceeding so that when you finally decide, it’s an informed decision.

Like how people usually go about purchasing property, buying IPv4 addresses is a process you need to plan carefully. There will always be several other contenders vying for the same resources as you, so you must consider all your needs before going ahead with this endeavor. And because there will always be others competing for what you want too, chances are that whatever price you offer would become obsolete if someone else were to bid higher than yours. To avoid being caught in this dilemma again, make sure to have done some research beforehand and find out the expected amount of money required before starting negotiations.

IP Lease for managing IPv4 scarcity

The deficit of the IPv4 addresses closely linked with technological limitation of the 32-bit code of the protocol IPv4, where is possible only 4,3 billion combination of the numbers. But is enough for the modern sector of information technologies, in which the quantity of the nodes in information technology is growing with the exponential rate. We will discuss if IP lease can be solution to fulfil needs of new customers.


The situation on IPv4 market and IP lease.

The companies that manage internet, announce that the addresses of the IPv4 protocol have come to an end. The cost for these sources is growing because of the deficit that has arisen.

According to our opinion, there are some alternative ways for the solving of the deficit issues, that could help to extend the lifetime of the protocol IPv4 and related equipment, and also without considerable investment in the purchase of new equipment and the disposal of the old, to make a gradual transition to the address space of the IPv6. The meaning of these ways is in thrifting the available address space of the IPv4 protocol.

growth in the number of LIRs
IPv4 waiting list


Volume of unused IP addresses and market demand

The reality is that more than 30% of the existing IPv4 address space is in a frozen, unused state, and an equal number of addresses are in a pseudo-used state. It applies to the whole address space IPv4 used in Europe.

The good illustration of the current situation, is for example, Germany, where in the presence of a shortage of IPv4 addresses of some firms and excess free addresses from others, there are practically no transactions between companies for their redistribution, the so-called transfer agreements.

IPv4 addresses hidden market Problems

Let`s go back to 30 years ago to the era, when the address space of the internet began to be shared among participants in the exchange of information. In that period the shortage of IPv4 was not so clear, and the address space was allocated to any organization, that asked for it, irrespective of her current needs.

Research institutes, state agencies and higher education institutes were the first to receive them.

The blocks allocated at that time could not be fully used, since the then participants on the Internet did not have such a number of nodes in their networks. Thus, unused addresses were safely forgotten.

But a huge number of blocks were once given to those who never planned to use them.

As a result, up to 30% of the world’s IP addresses at the disposal of various LIRs (Local Internet Registry), which is almost 1.3–1.4 billion, are now in a frozen state and are actually withdrawn from the world’s address space. 

The feature of accounting for network recycling in the regional RIR (Regional Internet Registry) registry does not allow you to look into the distribution lower than /24 and therefore such a network for the outside world, as well as for everyone who monitors this network from the outside, is considered to be fully occupied, and is not included in world statistics reports.

According to documents and on paper, we have a shortage of IPv4 addresses, but in reality there is no shortage, there are only organizations that use their IPv4 resources inefficiently and economically. These resources could be useful today for the development of the digital economy of any country if they could be shared with other Internet users. IP lease may help to solve this issue.


Ways to solve the problem of IP-address deficit.

Lean use of IPv4 space, redistribution of resources on IPv4 market.

First, it is necessary to reach out to the “sleeping” network owners who do not use these networks and offer them IP lease.

It is necessary to use lean approaches, which have recently been gaining popularity in Germany.

Transfer of data from owners of ip addresses to market

How to be „green“ in the market of IP addresses and at the same time to make profit?

The idea of opening up the market of unused IPv4 addresses as a global project which companies can contribute to

  • But here`s what anyone who suddenly discovers their owner can do with their free networks, we will briefly describe.
  • For example, an IP network with a size of /16 (65512 addresses) can bring its owner about 30,000 € per month when leased out with IP lease.
  • For IP lease, special trading platforms, the so-called Market Place, can be effectively used.

INTERLIR Marketplace

One of the few platforms under the jurisdiction of the European Union is the German MarketPlace Interlir.com, which was developed by our company Interlir GmbH.

With the help of our platform, you can redistribute the entire mass of IPv4 resources unused in Europe for practical use, offering everyone who really needs IPv4 addresses to lease them from their owners for a while and as needed on a reimbursable basis.


The idea of frugality as an aid to the IT market for further development.

  • In our opinion, it is possible to involve the state itself in the process of thrifty distribution of IP resources, which could, among other things, legally confirm the legitimacy of such an approach and encourage owners who have excess resources to participate in the redistribution.
  • In addition to real practical benefits for the IT industry and accelerating its development, as well as saving huge funds for equipment replacement, this can bring real benefits to those institutions – owners of IP resources that will participate in this.
  • The release of new address space will have a beneficial effect on the development of the IT market in the country and will allow developing and already established companies not to spend significant funds on the purchase of expensive equipment or on the purchase of IP address networks on the open market.
  • The other way is to conduct a global audit program on the use of address space in universities, government agencies and corporations, and develop a detailed plan that would allow moving and consolidating IP resources and freeing up the available address space for each specific enterprise.

The benefits of using the idea of frugality for the governmentand business. Using the Interlir platform in the idea of IPv4 Lean.

  • The vacated address space can also be distributed through the European platform Interlir.com among all participants in the IP resource market.
  • In this case, consumers will be relieved of the need to purchase address space from spontaneous IP brokers, as well as third-party and foreign enterprises at incomprehensible and, at times, non-market prices.
  • The obvious benefit of using the address space redistribution system makes our platform applicable, including at the state level, for the purpose of market regulation of the price of such resources.
  • Given that our system, using unique technologies, provides free access to IP resources to any market participant, we can confidently count on the use of our developments to create a nationwide system for market regulation of the IPv4 address space in Europe.

How to Lease IPv4 Addresses in 2022

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 2022. 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 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 2022 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 lease your unused IP addresses by creating 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.


IP 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, 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.

How to Monetize IP Network

Even if you have absolutely no intention of selling your IPv4 network, you can still monetize IP in specific ways. Whether you want to rent out unused IP addresses or sell your IP address space to another party, there are multiple options available to get some extra cash out of it, even if you don’t intend to stop using it yourself soon. Plus, if an IPv4 shortage ever hits the market and IPv4 prices skyrocket, you’ll be glad that you took the time to learn how to monetize your IPv4 network beforehand!


Why is it essential to monetize IP addresses? The Internet is growing exponentially, and in doing so, it has run out of space to allocate IP addresses. As IPv4 (Internet Protocol version 4) reserves for Internet service providers are depleted, internet engineers are forced to find solutions that allow IP addresses to be shared across multiple users. Without a proper solution in place, you will not be able to monetize your IPv4 network—meaning you will miss out on an essential source of revenue. To ensure you can adequately monetize your IPv4 network, you need to work with qualified experts who have extensive experience with various addressing methods. At Interlir, we specialize in monetizing IPv4 networks by implementing public IP address sharing solutions.

Our experts offer one-on-one consulting services and customized workshops explicitly tailored to each client’s needs. When choosing Interlir as your preferred provider for managing your IPv4 network, you can rest assured knowing our expert staff members have extensive experience with the technical and business aspects of sharing IP addresses between users.  With over 20 years of experience under our team belt, Interlir has developed a proven track record for making sure businesses can seamlessly share their public IP addresses. We pride ourselves on being flexible and willing to meet each client’s unique needs. We offer high-quality customer support at no additional cost to clients—which means you get personalized attention from start to finish when working with us. Whether you need help getting started or have questions about setting up specific features, we are here for you.


What are the benefits of obtaining an IP address pool?

If you own a business, you probably already know that your company’s IP address is essential in maintaining its internet presence. Businesses rely on IP addresses for everything from crucial functions (sending and receiving data) to more advanced uses (such as video conferencing). But what most businesses don’t realize is that they can actually capitalize on their IP address by utilizing it in multiple ways, not just online business. By obtaining a pool of unique IP addresses, you can take advantage of your web presence and turn it into a natural source of income. Let’s take a look at how… 

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

First, it’s common for people to believe that only one company is responsible for maintaining IP address space. Actually, five Regional Internet Registries (RIRs) manage and allocate blocks of IP addresses on behalf of their respective regions around the world. 

The second common misconception is that if you want an IPv4 address block for your business, you will be able to get one from one of these RIRs without any trouble. In reality, each RIR allocates blocks based on a set policy or plan. If you don’t fit into one of those plans, then you may not be able to obtain an IPv4 address block. 

Thirdly, some people think that they can avoid getting involved with IPv6 by simply obtaining enough IPv4 addresses to meet their needs. This isn’t true; while it might take longer for many organizations to run out of allocated IPv4 address space than expected, eventually, everyone will need additional addresses—or they won’t be able to grow their businesses!  


 One misconception is that it’s hard to monetize IP network and make it profitable. With Interlir, you can increase revenue by selling or leasing out your own and other networks’ unused or underused IP address space, guaranteed 100% safety. Find out more about how you can get started today!

 The Interlir team knows that there are many misconceptions about how easy it is to monetize an IPv4 network and have done away with those barriers by offering a completely automated and secure way to lease out your address space. Interlir is changing that. You get paid immediately into your own bank account after each transfer or renewal, so there’s no waiting around on any quarterly payments. This process could not be more straightforward. It really couldn’t be easier!



Who can help me obtain an IP address block or manage my existing one? Someone specializing in managing IP address blocks worldwide is called a Regional Internet Registry or RIR. A Regional Internet Registry (RIR) is a non-profit organization with members representing different world geographical regions. Each RIR is responsible for managing one or more publically routable IP address ranges and allocates smaller portions of its range to Local Internet Registries (LIRs), which give those portions to end-users. In most cases, an LIR must apply for and receive an allocation from an RIR before it can issue addresses directly to its customers. ARIN, RIPE NCC, APNIC, LACNIC, and AfriNIC are the five current RIRs. You may be able to monetize your existing IPv4 network by selling unused IP addresses within your network. Some companies specialize in brokering sales of IP address space on behalf of their clients. These companies will also manage many aspects of transferring ownership and registration as required by various regulatory agencies.

 While you can monetize your IP addresses directly with those who wish to purchase, most businesses that sell or lease IP address space do so through an intermediary. This intermediary is typically called a Registrar, Broker, Reseller, or Service Provider. In most cases, an organization will turn over management of their network and/or IP address allocations to a third party, providing all services related to managing network assets and existing IP allocation or outsourcing such assistance as appropriate. The exact process for selling or leasing IP address space varies by country and region. For example, in Germany (Deutschland), it is possible to transfer ownership of unused IP addresses without requiring approval from a regulatory agency. In other countries, however, companies wishing to broker sales of IP address space must apply for permission from a government regulator before making any sales.  Each country has a governing agency that oversees the allocations of IP address space. This is usually a non-profit organization established for that purpose and includes national RIRs and LIRs. In most cases, to broker transfers of IP address space, an intermediary must either operate from within a country or be incorporated there. A few countries, including Germany (Deutschland), allow businesses outside their borders to manage sales or leases of unused IP addresses on behalf of their clients without requiring approval from regulators first. If you are located in Germany (Deutschland), you can monetize your new IPv4 network using any brokers specializing in brokering sales of IP address space on behalf of their clients. 


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

The most significant decision you’ll make when monetizing your IPv4 network is how to market it. If you don’t have a network, here are some helpful tips: How to buy an IPv4 network

Once you’re ready, though, there are two common ways to monetize your IP address space. 

The first option is selling them directly as part of a more significant offering, such as a collocation service or multi-homing agreement. 

The second option is selling them through brokers and auctions. This can be trickier because of potential price fluctuations and less predictable returns, but you get better visibility of how much money your network makes each month.

And the last and most profitable way is to lease out your unused IPv4 networks with Interlir IPv4 marketplace.

 Interlir offers you a profitable price for your unused IPv4. If you are not ready to be out of business, it is an excellent way to keep your network online. 


Is this really the right solution for me to monetize IP?

This is perhaps one of the most common questions about network monetization. It boils down to: is it better for you to sell your IP address blocks or sub-allocated them? Is there even a difference? Let’s break it down. If you own an IP address block and have some primary use for that block, such as your company uses a /16 IP address block internally, then sub-allocates out a smaller /22 block to other internal networks. What are your options when that IP address space is eventually exhausted? 


Here are three options you might want to consider 

1) Release unused address space back into RIR

2) Sell or sub-allocate unused IP addresses

3) Reserve those addresses for future use  


 If you choose option 1, releasing unused IP addresses back into RIR, you have effectively no use for those address blocks. This can be a viable option if you are in a position where your usage has reached its peak.

If you choose option 2, sub-allocating those unused addresses to another party who will use them, then what are your responsibilities? Do you need to provide documentation proving ownership of those IP addresses? Do you need to track how many times those IP addresses are sub-allocated and ensure they don’t get exhausted again? The answer is yes! You must document every transaction involving your IP address block, including but not limited to:

  • When it was allocated.
  • When it was released.
  • When it was transferred from one entity to another and so forth.

What happens if one day an audit is performed by an external auditor or RIR representative (like ARIN) and they discover that there were some undocumented transactions involving your IP address space? Well… good luck explaining yourself! You must also maintain records indicating how often each individual /24 block within that /16 block has been allocated. 

Interlir has a solution; we will manage RIR databases for you; just sign a management agreement and set our maintainer interlir-mnt. The rest is our duty.


Now that you have your pool, what should you do with it? Monetize IP!

Now that you’ve got a big pool of IP addresses, what do you want to do with them? Why not monetize them and start making money? Turn it into a business – lease out your newly acquired IPs and make some money. But before you can decide whether selling your IPs is a good idea, here are some of the things you should consider: #Cost/Benefit Ratio. 


Final thoughts.

It is critical to consider which method you will use to monetize your IPv4 network. While there are several methods of doing so, you have complete control over what approach you take and how it impacts your company’s bottom line.

Why Buy/Rent IP Networks?

Several online services have been created to serve as marketplaces where anyone can buy and/or rent network address space, from small business owners looking to upgrade their current network address space, to service providers that want additional address space to host an expanding number of clients.

As a result, more and more IP network owners are willing to sell or rent their IP space. Anyone can rent unused addresses at affordable prices, paying only when using them. That is why we created our own IP network marketplace – Interlir. It is truly an international platform with over 20% of users originating from Germany and other significant user bases in France, Turkey, Poland, the UK, Brazil, and Japan.

Marketplace

Our IP network marketplace is an ideal way to purchase unused network address space and/or rent it out to those in need. With our user-friendly platform, you can effortlessly buy or sell IPv4 addresses with just a few clicks. We ensure that every step of the process goes smooth and seamless, providing all tools needed at the lowest prices on the market.

 The first time your order was made, we already got paid. You pay monthly you have ordered our service. Our revenue depends solely on your feedback, so we strive to please our customers by constantly improving our site’s selections of networks and the functionality of our site.

 You can purchase unused network addresses to /upgrade your current IP address space and rent them out to cover all or part of your hosting expenses. All purchases can be made using either credit cards, SEPA, or Giropay accounts, and if you don’t have either of those – we can accept cryptocurrency as an additional payment method. Since all transactions on our platform are protected with SSL encryption and carried out through Stripe secure payments, it’s a safe way to both buy and sell network addresses.

Scenario 2 – The Provider (Who Owns the IP Networks)

The provider has a network with public IP addresses (for example, /24 netmasks or bigger) that are not in use and are not assigned to anyone. Its parameters are defined to allow easy implementation into existing infrastructure without any problems. The provider signs up at Interlir and indicates available prefixes he wants to share with other people. Once registered at the platform (which takes 5 minutes), he can make a virtual shelf, similar to eBay’s auction page, where he lists his inventory. He will be ready to lease out.

 After the IP owner lists his inventory (that usually contains /24 to /16 netmasks), he does not has to wait till someone interested contacts him; it’s all up to Interlir to proceed with deals and setup IPv4 rent deal. All contracts between providers and network owners are signed privately, and all information is confidential. To protect the personal data of provider and network owner, all correspondence related to sales goes through the Interlir automated portal, which ensures that no data leaves our platform without necessity. All other marketplace participants can use an advanced filtering system, which allows them to show only those networks they are interested in.

New to the market?

With the INTERLIR solution at hand, even a novice user can start making money right away! The provider has nothing to do after somebody rents his IPv4 address. The whole transaction happens automatically and is under the control of Interlir administrators. Our platform changes required network parameters and automatically updates RIR databases in a short time. The new owner can work with it like its own network (he gets all the necessary information from our platform).

 Our platform takes care of all other aspects – it checks if there are no conflicts, verifies possible overlaps, and makes sure everything works as planned. When everything is ready, Interlir sends a confirmation email to both parties (provider and purchaser), which allows them to start using the new network without any problems.

IP Networks Owners

The owners of IP networks will be able to list their network address space on a marketplace and rent, lease out or sell it as needed. IP addresses are often not fully used at each network, so owners have many unused addresses that they are willing to give away and earn some money. This service will provide an online platform that allows IP networks owners to offer their unused IP address space, either on rent or sale. The aim is to drive up the turnover of IPv4 networks by giving end-users access to extra IP addresses instead of having them wait until new IP address blocks become available on a first-come-first-served basis.

 So, if you want to exchange or rent your unused IP addresses online at a market price and help accelerate IPv6 deployment simultaneously, you can sign up as an owner on the Interlir platform now! Our sales team will get in touch with you shortly after receiving your application and will prepare everything so that you can launch your network as a business partner with just a few clicks. If you are interested, don’t hesitate to contact us – just fill out our online form at portal.interlir.com! We hope many IP networks owners will join us soon!

Unused IPs

 Other companies that have unused IP addresses or need more IP addresses may also be interested in joining our platform. Our platform will provide you with an easy way to buy or rent additional IP address space, which can be routed using private networking solutions to your data center or other locations.

If you want to sell your entire network and move it somewhere else, we will help you find a buyer and ensure that all data is preserved throughout your migration. We are here for you! The potential of Interlir’s solution is already clear – It’s time to enable Internet access for everyone in a more efficient manner now!

The great IP address space redistribution

One of the possible ways to support the development of the IT sector is the effective use of existing IPv4 address space. Due to the rapid growth of information technology and many objects associated with the Internet, IP addresses of the old but reliably working protocol IPv4 have become scarce. And the introduction of a new protocol, IPv6, is associated with many technical and organizational difficulties and is still delayed for many years.

Interlir Marketplace for an IP address space

The deficit of the IPv4 addresses is closely linked with the technological limitation of the 32-bit code of the protocol IPv4, where it is possible for only 4,3 billion combinations of the numbers. But it is enough for the modern sector of information technologies, in which the quantity of the nodes in information technology is growing exponentially. There are a few numbers of the several ways to solve the deficit problem. For example, all IT market participants can use the IPv6 protocol, and it is possible to use also NAT (Network Address Translation) technology or other ways. 

But in the IPv6 protocol, for example, international security issues have not always been adequately resolved, and besides, the standard requires large expenditures for the purchase of new equipment. NAT cannot be used in all renewable sources. At the same time, there are always disadvantages associated with the timing of implementation or the cost of equipment.

In our opinion, there are some alternative ways to the solving the deficit issues that could help to extend the lifetime of the protocol IPv4 and related equipment, and also without considerable investment in the purchase of new equipment and the disposal of the old, to make a gradual transition to the address space of the IPv6. The meaning of these ways is in thrifting the available address space of the IPv4 protocol.

It seems to everyone that there is a global deficit in the accessible address space of the IPv4 protocol. The companies that manage the Internet announce that the addresses of the IPv4 protocol have come to an end. The cost for these sources is growing because of the deficit. 

In fact, there is no shortage whatsoever!

The reality is that more than 30% of the existing IPv4 address space is in a frozen, unused state, and an equal number of addresses are in a pseudo-used state. It applies to the whole address space IPv4 used in Europe. 

A good illustration of the current situation in Germany, wherein the presence of a shortage of IPv4 addresses of some firms and excess free addresses from others, there are practically no transactions between companies for their redistribution, the so-called transfer agreement.

Let’s explore this in more detail.

Let’s go back 30 years ago to the era when the address space of the Internet began to be shared among participants in the exchange of information. 

In that period, the shortage of IPv4 was not evident, and the address space was allocated to any organization that asked for it, irrespective of her current needs.

Where a /24 network (256 addresses) would be more than enough, a /16 network (65512 addresses) was allocated. No one counted the allocated sources, as there seemed to be enough for everyone and for a long time. Research institutes, state agencies, and higher education institutes were the first to receive them. Then IP addresses are allocated among the big corporations and firms. The blocks allocated at that time could not be fully used since the then participants on the Internet did not have such a number of nodes in their networks. Thus, unused addresses were safely forgotten.

Later, with the commercialization of the Internet, the distribution of IP addresses began to be carried out among Internet service providers, where the degree of utilization of IP addresses was already much higher. But a vast number of blocks were once given to those who never planned to use them.

As a result, up to 30% of the world’s IP addresses at the disposal of various LIRs (Local Internet Registry), which is almost 1.3–1.4 billion, are now in a frozen state and are withdrawn from the world’s address space. According to the latest report by RIPE NCC, only in Germany, about 40 million IP addresses are not explicitly used. They are managed by LIRs, which do not perform their function of allocating them. 

Most of these unallocated resources are in LEGACY or PI status.

No less of a problem with the remaining 70 percent of the address space. It is not a secret for anyone related to IT that chaos reigned in the distribution of address space at the stage of development of corporations and providers.

A simple example is that an enterprise has a /16 network consisting of 256 /24 networks, each consisting of 256 IP addresses.

Once upon a time, the trend was that the system administrator allocated a /24 network for each new project without really thinking about how many nodes in the local infrastructure it should serve. As a result, the division used 5–10 IP addresses, but since the route was set to the entire network, the whole/24 network was displayed by the system administrator as fully occupied.

The feature of accounting for network recycling in the regional RIR (Regional Internet Registry) registry does not allow you to look into the distribution lower than /24. Therefore, such a network for the outside world and everyone who monitors this network from the outside is considered to be fully occupied and is not included in world statistics reports. There are many examples of such careless use of IP resources.

One large German corporation, whose name we will not name, started a new project requiring a /24 network. It suddenly became clear that despite the corporation having at least 500 such networks, none could be allocated for the project. Because they are all busy, it turned out that the company’s admins always given at least a whole /24 network (256 addresses) for each new project or created service, even though only 5-10 IP addresses could actually be used in it. Moreover, these addresses were issued chaotically and could be random, not optimally, scattered throughout the dedicated network. As a result, the project could not obtain the necessary networks for its work.

It turns out that with all the networks occupied “on paper,” a large enterprise can use only 15–20% of the entire address space it has. The other addresses are not used. And it is complicated to correct this situation since network optimization by moving network nodes scattered throughout the IT landscape into one network is a global problem that is difficult to solve for any corporate system.

According to the documents and on paper, we have a shortage of IPv4 addresses, but in reality, there is no shortage; there are only organizations that inefficiently and not frugally use their IPv4 resources. These resources could be helpful today for the development of the digital economy of any country if they could be shared with other Internet users.

What are the possible ways to solve this problem?

First, it is essential to reach out to the “sleeping” network owners who do not use them. Our analysis of the state of existing IP resources shows that many owners of IP resources do not see them, maybe because these resources were apparently forgotten over time. It is necessary to use lean approaches, which have recently gained popularity in Germany.

How to find unused IP networks in your enterprise is a topic for another large article. The fact is that today, IP addresses can be easily turned into money. They can be sold, and they can be rented out. But here’s what anyone who suddenly discovers their owner can do with their free networks, which we will briefly describe.

For example, an IP network with a size of /16 (65512 addresses) can bring its owner about 30,000 € per month when rented out. And many owners of such networks do not imagine that they are sitting on enormous wealth.

Special trading platforms, the so-called Market Place, can be effectively used for renting. Such platforms exist in the United States of America, England, in China. The only trading platform under the jurisdiction of the European Union is the German MarketPlace Interlir.com, which was developed by our company Interlir GmbH. With the help of our platform, you can redistribute the entire mass of IPv4 resources unused in Europe for practical use, offering everyone who needs IPv4 addresses to rent them from their owners for a while and as required on a reimbursable basis.

In our opinion, it is possible to involve the state itself in the process of thrifty distribution of IP resources, which could, among other things, legally confirm the legitimacy of such an approach and encourage owners who have excess resources to participate in the redistribution. In addition to real practical benefits for the IT industry and accelerating its development, as well as saving enormous funds for equipment replacement, this can bring tangible benefits to those institutions – owners of IP resources that will participate in this.

For example, there are already universities in the USA that finance their current activities by renting out excess address space.

The release of new address space will have a beneficial effect on the development of the IT market in the country. It will allow developing and already established companies not to spend significant funds on purchasing expensive equipment or the purchase of IP address networks on the open market.

The other way is to conduct a global audit program on address space in universities, government agencies, and corporations and develop a detailed plan that would allow moving and consolidating IP resources and freeing up the available address space for each specific enterprise. Only a few firms in the world have unique experience in such an audit.

Interestingly, a relatively large number of IP addresses are managed by government agencies. That is why the state can play a decisive role in this process. The vacated address space can also be distributed through the European platform Interlir.com among all participants in the IP resource market. In this case, consumers will be relieved of the need to purchase address space from spontaneous IP brokers and third-party and foreign enterprises at incomprehensible and, at times, non-market prices.

The obvious benefit of using the address space redistribution system makes our platform applicable, including at the state level, for market regulation of the price of such resources.

Given that our system, using unique technologies, provides free access to IP resources to any market participant, we can confidently count on the use of our developments to create a nationwide system for market regulation of the IPv4 address space in Europe.

Considering that our system, using unique technologies, provides free access to IP resources to any market participant, we can confidently count on the use of our developments to create a nationwide system for market regulation of the IPv4 address space in Europe.

What is IPv4 address?

Short introduction to internet protocol addresses IPv4 address, or Internet Protocol address, is a unique identifier that points to each device on the internet and allows them to communicate with each other in order to send and receive data. Without IP addresses, the internet would not be able to work as it does today, and most of our electronic devices would not be able to access any data online without them. That’s why understanding IP addresses, how they work, and how they are created can help you better understand the internet as a whole, especially if you’re looking to get more involved with computer networks and web programming in general.


Let’s explain IP addresses in plain English. IP stands for Internet Protocol, which means it’s a set of rules used to identify your computer on a network. There are two main kinds of IP addresses: IPv4 and IPv6. They each have their pros and cons depending on what you’re looking for.

The good news is that most ISPs offer both versions now, so you can pick whatever one works best for your business needs. Both types of IP addresses are hierarchical; they’re broken up into four or six parts octets.

Each section represents a different part of an IP address and its relevant information. It also plays a significant role in why organizations use routing protocols to manage IP address allocation. As long as everyone uses them correctly, they work like a charm. Of course, not everyone wants to do that—or has room for that many addresses in their system yet (they’re expensive!).

So how does data get through these IP nets then? At least some internetworking protocol exists between them to make sure data gets passed along successfully. The actual process depends on how well connected everything is! This is where subnetting comes into play;


What is subnet ?

subnetwork or subnet is a logical subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting.

For IPv4, a network may also be characterized by its subnet mask, the bitmask that yields the routing prefix when applied by a bitwise AND operation to any IP address in the network.

For example, the prefix 190.21.100.0/24 would have the subnet mask 255.255.255.0. Subnet masks are expressed in dot-decimal notation.

For example, 190.21.100.0/21 is the Internet Protocol version 4 network prefix starting at the given address, having 21 bits allocated for the network prefix and the remaining 11 bits reserved for host addressing.

Traffic is exchanged between subnetworks through routers when the routing prefixes of the source address and the destination address differ.

Subnetting may also enhance routing efficiency or have advantages in network management when different entities in a larger organization administratively control subnetworks.

Subnets may be organized logically in a hierarchical architecture, partitioning an organization’s network address space into a routing structure.


IPV4 vs. IPV6 Explained

IPV4 (IP version 4) is what we currently use to connect to websites and servers, but it has a number of problems. For one, IPV4 addresses are running out. An IP address is simply an assigned number used by your computer or mobile device to access content on a network. We need new addresses because we’re nearly out of them. However, IPV6 (IP version 6) solves that problem as it can provide 2128 possible unique addresses for every human being on Earth.


What’s the difference between an IPv4 IP and an IPv6 IP?

IP stands for Internet Protocol, and in general it refers to a device’s specific location on a network. But that term can be confusing because there are two types of IPs—IPv4, which was created in 1981; and IPv6, which was only fully implemented recently. If you’ve got a device connected to your home router or office computer system, chances are you’re using an IPv4 IP address.

That being said, both versions actually fall under one category—in other words, they’re both IP addresses. The main difference between them is their size (IPv4 is 32 bits long and IPv6 is 128 bits long), but that doesn’t have much practical use for consumers yet; typically IP addresses will just look like strings of numbers separated by dots. Since most computers now support both protocols, it might not matter which type you use when browsing online.


What is the IPv4 address structure

What is IPv4 address in a computer network? All IP addresses are a series of four numbers, from 0 to 255. Each is separated by dots (periods). Each number can be any number between 0 and 255. For example, if the address is 212.168.0.0, then the first number would be 212, the second 168, the third 0 and the fourth 255.


What is the IPv6 address structure

The Internet Protocol version 6 (IPv6) is the latest Internet Protocol version. IPv6 is a network layer protocol for packet-switched internetworking and provides end-to-end datagram transmission across multiple IP networks.

It was designed to replace the current protocol, IPv4, which is reaching its maximum capacity. The IPv6 address structure is hierarchical and consists of 128 bits—compared with 32 bits in IPv4. Each bit in an address represents a number from 0 to 256; if a bit is set to 1, it’s part of the address.

The protocol implementation has been separated into two layers: addressing and routing. Addressing determines where packets should be sent next; routing decides how to get there.

IPv6 addresses are eight groups of four hexadecimal digits each, separated by colons. Since each digit can represent up to 16 numbers, each group contains four or eight digits altogether. Every device connected to an IP network must have one or more globally unique IPv6 addresses associated with it.


Why we run out of IPv4

IPv4’s unique addressing scheme requires that each device connected to a network be given its individual IP address. Unfortunately, IPv4 can only support 4.3 billion devices on a single network;

IPv4 can run out at any time, and Internet Service Providers (ISPs) are already running out of IPv4 addresses to give out for new customers. The world has no choice but to replace IPv4 with an alternative addressing scheme like IPv6.


Who needs IPv4 and IPv6 addresses

But behind that number exists an entire network of computers, which can be vulnerable to attack. Get an IP address wrong, and your data could be sent to another server or even cause damage to someone else’s system. Do yourself (and others) a favor by getting your IP address right.

Even if you don’t own your IP address, you can still have one assigned to you from companies that specialize in selling them. Just as businesses go out of their way to ensure people find their physical location on a map, they also want their IP address communicated clearly.

Companies purchase large blocks of IP addresses to distribute them among branches and other sites, so they’re easy for customers and prospective partners alike to find them online. By giving each site its unique IP number, businesses ensure their headquarters has a recognizable IP address ready when visitors look up its information online.


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

  • Internet service providers
  • Hosting Companies
  • Cloud Services
  • VPN services
  • Various Internet Businesses
  • Banking and payment services


LIR and RIR

Most IP addresses are owned by LIRs (Local Internet Registry). An LIR will get IP space from RIR (Regional Internet Registry), often in blocks that are administered for private use within a geographical region. Each region keeps track of how much IP space it has available, how many accounts it has registered to assign with those spaces, and who should get what block next. ARIN is responsible for administering IP addressing space within North America, while RIPE NCC does so within Europe and Africa.

There five RIRs and each covers specific geographical regions :

  • ARIN
  • RIPE NCC
  • APNIC
  • LACNIC
  • AFRINIC
