How Regional Internet Registries Should Adapt to Current Markets

Outdated policies at Regional Internet Registries hinder the efficient transfer and leasing of IP addresses, driving up internet costs in emerging markets and limiting innovation. A faster, more inclusive governance model is urgently needed.

Internet Evolution: Moore’s Law, Addressing Architectures, and the Future of Internet Scale

The Internet has evolved from a scarcity-driven system into one defined by abundance, reshaping infrastructure, governance, and economic models while challenging long-held assumptions about addressing, network roles, and the future of protocol design.

Entering the Growing IPv4 Market: What Enterprises Should Do Now

With IPv4 addresses fetching up to $30 apiece and IPv6 adoption lagging, companies may be sitting on hidden digital assets. A strategic audit could unlock unexpected revenue and enhance long-term infrastructure planning.

RIR Gainers and Leakers: How Policy Choices Shape the Future of the IPv4 Ecosystem

Diverging policies and fee structures among Regional Internet Registries are reshaping the global IPv4 market. RIPE has emerged as a liquidity hub, while others leak resources, risking long-term instability and financial fragility.

2025 IPv4 Price Trends and 2026 Predictions

Through 2024, IPv4 leasing stayed steady at about $0.50 per IP per month, even as purchase prices diverged by block size. Large blocks (like /16) corrected notably while smaller blocks (/20 - /24) remained comparatively firm. That spread reflected shifting enterprise behavior (more surgical allocations, less speculative buying) and the resilience of subscription-like leasing in unstable conditions.

The 2024 IPv4 Market in North America

Between 2021 and 2023, the IPv4 market was a roller coaster ride - prices shot up in 2021, peaked in 2022, and plummeted in 2023. Those who expected a recovery in 2024 were sadly disappointed. Prices for IP addresses continued to decline, leveling out during the second half of the year. And yet, market activity remained remarkably unaffected - a sign, perhaps, that the market is settling into a new normal.

Cogent Communications Offers $206 Million in Secured Notes Backed by IPv4 Addresses

Cogent (CCOI) recently announced that it was offering secured notes for $206M. The unusual part is what it’s using as security: some of its IPv4 addresses and the leases on those IPv4 addresses... Cogent has been leasing out addresses for several years. All internet service providers (ISPs) give IP addresses to their users, but Cogent was among the first to lease those addresses independently of internet access.

The 2023 IPv4 Market in North America

In 2021, the story was price. In 2022, the story was price and large block supply. The story in 2023 is decline -- but with a notable caveat. Spurred by unprecedented unit pricing, the North American IPv4 market in 2022 experienced its second-best year in terms of overall traded volume, and in both 2022 and in 2023, large block market activity was as robust as ever, with sellers trading large blocks at over $50 per number.

What Happened to IPv5, IPv7, IPv8 and IPv9?

The IPv4 market has created serious interest in the protocol far beyond the natural confines of networking professionals. These assets are worth a lot. Marketplaces, IPv4.Global's especially, have grown to be large centers of asset transfer by buyers and sellers of IPv4 addresses. IPv4.Global has helped transfer over $1 billion in IPv4 blocks.

What is Bring Your Own IP (BYOIP)?

An IPv4 address identifies your connection to the online world. IP addresses make it possible to host websites, manage secure communication, and engage in countless other essential, internet-related activities. Typically, when migrating to a new cloud provider, a business has only one path: lease the provider's IP addresses. But what if a business already has a block of IP addresses?

AWS Sets the ROI Benchmark for IP Addresses

In a rapidly evolving digital landscape, the value of IP addresses has surged to the forefront of discussions. Over a month ago, Amazon Web Services (AWS) made a pivotal announcement, reshaping the IP address pricing landscape. Citing the escalating costs of acquiring IP addresses on secondary markets, AWS declared a fundamental shift in its pricing strategy, set to take effect on February 1, 2024.

IPv4 Prices: Supply and Demand in 2023

In early 2022 the discount that had been available for large blocks of IPv4 addresses disappeared. For the first time in years, /16 blocks and larger began to sell at an increasing premium. By Q2-2023, small and medium-sized blocks sold for a 30-35% discount to larger ones. At the same time, the tighter range of prices that had persisted for nearly a decade fractured and blocks traded in wide ranges throughout 2022 and the first half of 2023.

Opinion: IP Leasing Should Become a Market Standard

The Regional Internet Registry (RIR) for the Asia-Pacific region (APNIC) recently held its 55th meeting in conjunction with APRICOT, from 20 February to 2 March 2023, in Manila, USA. One of the critical discussions at the conference was centered on the APNIC policy that does not accept IP leasing and has a questionable understanding of its necessity. According to the APNIC policy manual, which was referenced during the meeting, APNIC allocates and assigns resources based on need, and 'leasing is not allowed' nor does it form a basis for further need.

The 2022 IPv4 Market in North America

In 2021, the story was price. In 2022, the story was price and large block supply. Spurred by unprecedented unit pricing, the IPv4 market in North America experienced its second-best year ever in market history. Nearly double the number of IPv4 addresses were traded in 2022 compared to 2021, predominantly due to the increased flow of large block supply from twelve sellers, five of whom were first-time market participants.

The IPv4 Price Inversion

A curious price inversion has occurred in IPv4 markets. The long-term trend that discounted large blocks has reversed. The graph identifies /15 and /16 (large) block pricing per IP address throughout the period in the form of dark spots. It is evident that, for most of the timeframe here (2014 to the first half of 2021), large blocks sold at a significant discount. One might guess that the administrative chores related to large-network needs were most efficiently and cheaply satisfied with large blocks.
