IPv4 Markets / Recently Commented

Running-Code Primacy - The Patch Needed to Preserve the Internet’s Original Design

This essay argues that Internet governance has drifted from technical coordination into unaccountable institutional power, and proposes "Running-Code Primacy" as a post-RIR framework grounded in distributed validation, interoperability, and voluntary adoption rather than registry authority. more

Registry Under Siege: Investigating NRS Outreach to AFRINIC Members

As AFRINIC rebuilds after years of litigation, the Number Resource Society is urging members to sign powers of attorney, raising fears that coordinated advocacy, commercial interests and geopolitical pressures could reshape African control over critical internet resources. more

China and the Geopolitics of Africa’s 6.2 Million IPv4 Addresses

AFRINIC's fight over 6.2 million IPv4 addresses exposes how legal pressure, offshore vehicles and scarcity economics can strip Africa of leverage, turning a technical dispute into a test of sovereignty, institutional resilience and Internet governance. more

Mandate Laundering: From RIR Fantasy to Transition Architecture

Private internet registries have inflated narrow technical roles into quasi-sovereign authority, laundering mandate through ritual and rhetoric; a fragile system now faces legal, economic and political reckoning, prompting calls for coordinated transition urgent global reform. more

Africa Can’t Skip IPv4 on the Road to IPv6

Africa's push toward IPv6 cannot bypass IPv4 scarcity, as uneven infrastructure, market dynamics, and governance disputes raise costs, entrench inequality, and risk turning transitional address shortages into a lasting brake on digital development across regions. more

The Misinformation War Over Africa’s Internet Registry

Afrinic crisis exposes how legal pressure, proxy advocacy and owned media reshape narratives, potentially threatening global internet registry governance and shifting Africa's IP resources from public stewardship toward market commodification with broader far-reaching institutional consequences. more

We Kept Saying IPv4 Prices Would Rise Again. Did Anyone Listen?

After a prolonged slump, IPv4 prices are rising as tightening supply meets sustained demand from cloud and AI infrastructure, signalling a market correction and diminishing opportunities for buyers who had delayed acquisitions. more

China, AFRINIC, and the Dangerous Precedent That Could Destabilize the Global Internet

A dispute over 6.2m IPv4 addresses at AFRINIC exposes how litigation and market incentives could erode regional stewardship, setting a precedent that risks turning the Internet's allocation system into a vehicle for global arbitrage. more

Africa Is Not a Digital Quarry

Africa's internet registry crisis reflects not abstract design flaws but sustained legal and market pressure, as scarce address resources are drawn into global arbitrage, challenging stewardship and exposing the fragility of regional digital governance. more

The Hyperscale IPv4 Moat: Analyzing AWS’s Latest 9M Address Acquisition

AWS has quietly acquired nine million more IPv4 addresses, turning internet scarcity into strategic leverage. As hyperscalers consolidate dwindling supply worldwide, IPv4 is evolving from legacy protocol into a profitable infrastructure moat for cloud giants. more

NANOG 95: From Faster Fibre to Route Leaks, Operators Face Old Problems with New Tools

The NANOG 95 conference spotlighted breakthroughs in fibre optics, wireless technology, routing security, and quantum computing, offering a forward-looking assessment of internet infrastructure and its vulnerabilities, as reported by APNIC's Geoff Huston. more

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. more

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. more

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. more

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. more
