How IPXO Enables Revenue for Businesses

Businesses can generate recurring revenue from unused IPv4 addresses by leasing them instead of selling them outright. IPv4 monetization allows IP holders to keep control of their address space while earning income from resources they do not currently use. IPXO Platform supports this process through an IPv4 leasing marketplace, subnet validation, abuse monitoring, reputation management, automated payouts, and tools that help businesses lease IPv4 resources safely and transparently.

IP addresses are the foundation of internet connectivity. They identify devices, support routing, and make it possible to connect to one another on the global computer network. As IPv4 resources have become scarce, it is evident that this resource offers interesting opportunities for businesses.

It’s a fact that we are running out of some of our IP addresses at an inordinate speed. While we will not deplete IPv6 addresses any time soon – if ever – we have already exhausted IPv4 addresses. What’s the difference between IPv4 and IPv6? There are 340 undecillion IPv6 addresses but only 4.29 billion IPv4 addresses.

Although IPv6 is meant to replace IPv4, it remains widely used across networks, applications, and infrastructure. In addition, we have found ways to cope with the exhaustion of Internet Protocol version 4 addresses. For example, thanks to Network Address Translation (NAT), we can consolidate IP addresses, which means we need fewer of them.

All in all, more and more IPv4 addresses are in demand, and with IPv4 supporting the internet, we cannot function without this resource yet. Surprisingly, some 800 million IPv4 addresses remain unused, creating a revenue opportunity for businesses that hold address space but do not currently need it.

Unused IPv4 addresses: a business opportunity

The IPv4 address shortage has shaped internet infrastructure for decades. When the Internet Protocol version 4 (IPv4) emerged in the 1980s, 4.29 billion addresses seemed sufficient. However, rapid internet growth in the 1990s made it clear that the global address pool would eventually become limited. IPv6 was introduced in 1995 as the long-term successor to IPv4, but this version hasn’t fully replaced IPv4 yet.

As a result, many businesses still depend on IPv4 for connectivity, hosting, cloud infrastructure, telecom services, and other network operations. This continued demand has led to IPv4 becoming a commodity: a scarce, market-driven resource that is bought, sold, and sometimes compared to gold, stocks, or cryptocurrency. As demand for IPv4 addresses remains high, the value of this once-free resource is now shaped by factors such as supply, reputation, region, and block size.

IANA (Internet Assigned Numbers Authority) coordinates the global IP address space and officially distributed the last free IPv4 address blocks back in 2011. Since then, a secondary market has emerged, where buying and selling IP addresses have become the new norm.

Four Regional Internet Registries (RIRs) also facilitate inter-RIR transfers. While APNIC, ARIN, LACNIC, and RIPE NCC RIRs freely transfer resources among themselves, AFRINIC ratified a Number Resources Transfer Policy in February 2026 that formally allows inter-RIR transfers under specific conditions and where reciprocal policies exist. However, AFRINIC’s participation still depends on implementation status, transfer compatibility, and eligibility requirements between the involved registries.

IPv4 brokers

Ultimately, we all need IPv4 addresses to connect via the internet. Therefore, it is not surprising that the secondary market is booming. In fact, it’s no longer a new market. Microsoft has been buying IPv4 resources for at least a decade now. In 2011, for example, it purchased 666,624 IPv4 addresses from Nortel for 7.5 million USD using the services of an IPv4 broker.

Numerous IP brokerages exist these days, and they assist both buyers and sellers of IPv4 resources. When it comes to selling IPs, brokers are responsible for finding prospective buyers and striking the best deals to make the most money for the IP holders. Those looking to buy IPs use brokers’ services to find reputable and usable resources at reasonable prices.

Unfortunately, many IP addresses that are re-distributed have a poor reputation and plague IP blocklists. Brokers assist buyers in finding IPv4 resources that are clean. However, they are unlikely to help with delisting IPs from blocklists.

IPv4 lease market

As IPv4 address space became harder to obtain, the secondary market expanded beyond buying and selling. Some IP holders choose to wait before selling unused resources, especially when market conditions are uncertain. At the same time, small and mid-size businesses may not have the budget or long-term need to purchase scarce IPv4 addresses outright.

This is where IPv4 leasing became a practical alternative. Leasing allows businesses to access IPv4 resources without a large upfront purchase, while IP holders can monetize unused address space without permanently transferring it. Instead of keeping IPv4 resources idle or selling them outright, holders can lease them to organizations that need IPv4 capacity, generating recurring income while preserving future flexibility.

How has the IPv4 market changed?

IANA allocated all 4.29 billion IPv4 addresses for free. The RIRs responsible for distributing the resources in their service regions did not charge for IP addresses either.

In the 1980s, when IPv4 emerged, anyone with a legitimate reason to own IP addresses could easily request and obtain the resources. However, as we started running out of IPs, and especially after IANA allocated the last unused IP addresses, RIRs started implementing much stricter protocols.

Today, RIR allocations are limited and policy-dependent. Depending on the region and eligibility requirements, organizations may receive small allocations such as /24, /23 and, in some cases, /22 blocks that consist of 256, 512 and 1,024 IPs, respectively, but the rules differ between RIRs. For example, ARIN allocates IPs to critical infrastructure providers only, and LACNIC allocates IPs to members who have not received them yet.

Although some RIRs still manage limited IPv4 distribution, many organizations now obtain address space through transfers, purchases, or leases. The biggest market shift is that IPv4 is no longer a freely available resource.

IPv4 prices remain market-driven

IPv4 prices have changed significantly over the past decade. While the average price per IPv4 address was around $15 in 2017, it went up to $20 in 2018 and 2019. In 2020, buyers spent an average of $25 per IP address. In 2021, IPv4 sale prices shot up to around $44-50 per IP. A significant increase compared to the previous years. What has influenced that? In short, the increasing demand. The explosion of IoT plays a huge role in this. As more and more people got connected to the internet and bought internet-connected devices, IPv4 addresses became a desired commodity due to their scarcity and high demand.

IPv4 lease prices have also accelerated, and it is clear why. First of all, lease prices reflect the IP sale market, and if sale prices are going up, lease prices go up too. Second, IPv4 leasing has become more popular. Not only among those who may be unable to buy the resources they need, but also among those who have unused IPs that can be monetized.

After years of steady growth and a sharp increase around 2021-2022, the market adjusted in 2026. Pricing now depends on block size, RIR region, IP address reputation, and lease or transfer conditions. However, even with market fluctuations, IPv4 scarcity continues to support the need for usable address space.

Selling IPv4 vs. leasing IPv4: which is better for business?

According to our market stats, IPv4 lease prices range from $0.26 to 0.68 per IP (per month), depending on the address block. This is not a costly option, even if you need a larger IP block.

Of course, a /16 block consisting of 65,536 IPs would cost around $38,000 per month at the average price of $0.59 per IP. However, not all companies need this volume of IP addresses. The /24 block is one of the more popular in the lease market. There are 254 usable IP addresses in this block that can be leased for as little as $89 per month, which is plenty for many small to mid-size businesses.

What about IP holders? Is it better to sell the assets you’re not using? Perhaps you should keep them safe until you are ready to sell? Maybe leasing is the right move?

The tool shows how you can make more money by leasing IPv4 addresses for a single year than by selling once.

In a webinar hosted by IPXO, Dan Handy, working at the Ace Data Centers and Alex Latzko, the Principal Network Architect at Deft, shared their experiences with leasing IPv4 addresses via the IPXO Platform.

What does the IPXO Platform offer?

The IPXO Platform is the first fully automated IP address lease and monetization platform. In 2020, the service was developed as the IP Address Market under the Heficed brand. In August 2021, the Platform emerged as a standalone service under the IPXO brand.

The IP monetization service offered by the IPXO Platform enables IP holders to import their resources, set their own prices and lease IPv4 addresses to reputable parties.

The IP lease service enables those looking for clean and reputable IPv4 resources to filter subnets by CIDR (Classless Inter-Domain Routing), pay for the resources they need in just a few clicks and also assign IPs to any network.

IPXO features

The IPXO Platform offers tools that can help both lessors and lessees get exactly what they need. These services include:

• Full automation
• IPAM (IP address management)
• IP reputation management
• Abuse management
• DNS management
• Delegated RPKI
• IP geolocation

The IPXO Platform offers fully automated services, and clients can start monetizing or leasing pretty much as soon as they create their accounts, validate resource ownership and meet compliance requirements.

All payouts are automated, which means that earnings are transferred automatically at the chosen payout cycle. Conveniently, a standard 5% platform fee for IP holders is deducted monthly only once the subnets are monetized.

IPXO takes IP reputation extremely seriously. Disreputable IPs that exist in IP blocklists cannot be added to the platform, which ensures that clients only monetize and lease clean IPv4 addresses. Once IPs are in the platform, we continue monitoring them to ensure a stable IP reputation and to maintain the value of the resources.

Managing IP resources is extremely easy with IPXO’s IPAM dashboard. This ensures that all clients have full control. Even more control comes from delegated RPKI and IP geolocation services. To learn more, we invite you to watch the webinar recording introducing the IPXO platform.

How does IPXO handle abuse?

IP reputation is central to IPv4 monetization. If leased addresses are used for spam, malware, phishing, or other abusive activity, their value and usability can decline. This is why IPXO combines pre-listing subnet checks, business verification, KYC, abuse monitoring, and ASN blocklist controls to help protect both IP holders and lessees.

Experienced anti-abuse professionals employ automated abuse reporting and real-time monitoring to catch and mitigate abuse incidents in time. IPXO’s Market Stats show that 98.22% of abuse cases are handled automatically, while 1.78% require manual handling. Our team also works hard to make sure that all clients are audited before they can access the Platform to ensure security for everyone.

Whenever IP holders add their subnets to the Platform, we perform a thorough background check on IP addresses. With the help of almost 200 different blocklists, anti-abuse experts can make sure that only clean IP addresses are listed on the IPXO Platform. Even if a single IP address fails the check, the entire subnet cannot be added until it is clean.

Once the subnets are in the Platform, IPXO takes the responsibility to ensure that the IP addresses are utilized safely. A major undertaking for the anti-abuse team. Besides inventory control and screening, additional procedures include:

• Business verification
• KYC (Know Your Customer)
• ASN blocklist maintenance

At IPXO, every new business is verified manually so that only legal business entities monetize and lease IP addresses via the Platform. Businesses also need to fill out the declaration of usage form, which is one of the steps in the KYC process. This allows collecting data on the client’s GDPR compliance, mailing activities, the size of the company, etc. This enables to block unreliable parties from joining the Platform.

IPXO also maintains a blocklist of malicious autonomous system numbers, or ASNs. This list combines the unique database created by IPXO and Spamhaus’ ASN blocklist. Paulius Judickas, the Head of Sales at IPXO, explains the importance of ASN blocklisting:

Integration partners can significantly expand their toolsets by bringing IP management directly to their customers. You can fill a partnership form on our Partners page to contact our Sales team and get more information.

Scale and unlock a stable revenue stream using IPv4 addresses

IP addresses help build and scale businesses. Unfortunately, at this time, there aren’t enough IPv4 addresses to support everyone. This is, in part, due to IP holders keeping their resources unused. In fact, nearly 20% (around 800 million) of all IPv4 addresses are not serving anyone.

Bringing unused IP addresses back into the market helps new businesses access IPv4 resources and continue scaling despite IPv4 scarcity. This is easy to do using the IPXO’s Platform, a platform designed to help monetize and lease clean IP addresses in a safe, transparent and automated way.

Monetizing IPs is a great alternative to selling. While some IP holders choose to sell their resources, this is not always the best option. First and foremost, monetizing IPv4 addresses is more profitable in the long run. Second, with IPv4 prices softening in 2026, selling now might not be the best use of the resources. Finally, if a business is thinking about selling IPs in the future, leasing can offer a steady revenue stream until the final sale.

For businesses that need IPs, leasing offers an opportunity to scale without huge investments. Buying IP addresses requires a lot of money upfront. On the other hand, IPv4 leasing providers offer an opportunity to scale at low upfront costs.

To sum up, IP leasing helps build a sustainable internet that supports businesses of all sizes in dozens of unique industries. The doors are open.
