Everything You Need to Know About IPv4 vs. IPv6

The Hidden Value of IPv4 Addresses and How to Take Advantage of Rising IPv4 Address Value

Blogs

The Logic, Fallacy and Flaws Associated With IPv4 Network Resource Transfers

Fifteen years after IPv4 exhaustion, a transfer market has reallocated scarce address space, enabling internet growth, despite uneven registry policies, opaque fees, and lingering resistance to a system that proved more pragmatic than planned reclamation.

Regional Internet Registries’ Thick Governance Turns Uniqueness Into Double Extraction

Regional Internet registries, built for coordination, now sit atop scarce IPv4 assets while bearing little liability, suppressing capitalization and imposing "double extraction" that weakens operators, distorts markets and threatens the stability of global internet uniqueness.

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.

Internet Number Resources Are Not Political Property

Internet number resources, once clerical entries, now underpin real economic value, exposing a mismatch between registry power and accountability, while misplaced political narratives obscure the case for decentralised, operator-led control.

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.

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.

When Registry Power Detaches From Liability, It Detaches From Reality

IPv4 scarcity turned regional internet registries from clerks into gatekeepers of a valuable resource. Yet liability caps remain trivial, leaving powerful institutions with little accountability and incentives for conflict and structural breakdown ahead.

The Internet No Longer Needs Permission

Governance rules built for the early Internet are struggling to keep pace with a global, automated network. As IPv4 markets mature and infrastructure becomes software-defined, registries may need to prioritise transparency and automation over permission.

The Ghost Asset on Telco Balance Sheets: Using IPv4 to Fund the AI Transition

Hidden on telecom balance sheets, legacy IPv4 address space is emerging as a monetizable asset. Leasing underutilized blocks can generate recurring cash flow that helps fund AI infrastructure, modernization, and network investment without increasing debt.

What Drives IPv4 Demand in Today’s Market?

Predictions of IPv4's demise were premature. A market webinar shows demand has diversified, prices reflect structure not relevance, and leasing, policy shifts and broadband funding will keep the ageing protocol strategically important for years ahead.

Why Universities Should Monetize Their IP Addresses Instead of Selling

Universities sit on vast reserves of IPv4 addresses -- a legacy from the early internet. Instead of one-off sales, leasing these assets could generate sustainable revenues while preserving long-term digital infrastructure and institutional flexibility.

IPv4 Leasing: Myths vs. Reality

IPv4 leasing divides opinion as concerns over abuse, sustainability, and obsolescence persist. A recent IPXO webinar examined the evidence, challenging myths and advocating for transparency, flexibility, and cooperation in a shifting internet landscape.

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.
