• Scarcity of IPv4 addresses is driving a growing secondary market, with blocks increasingly traded, leased and valued like financial assets.
• The trend raises questions about transparency, regulation and the long-term impact on internet governance and access.
From Networking Necessity to Market Commodity
Internet Protocol (IP) addresses are the numeric identifiers that enable devices and networks to communicate online. The long‑established IPv4 protocol supports just over four billion unique addresses — a finite number that has long been anticipated to run out as global internet usage expanded. By the early 2010s, the global authority for internet resource allocation, the Internet Assigned Numbers Authority (IANA), had exhausted its free pool of IPv4 addresses and delegated the remainder to regional internet registries (RIRs). Since then, the publicly available supply of new IPv4 addresses has essentially disappeared, even as internet users and connected devices continue to multiply.
In response to this scarcity, markets for the transfer, sale and leasing of IPv4 address blocks have grown. Early private trades date back over a decade, with notable transactions such as Microsoft’s acquisition of hundreds of thousands of IPv4 addresses from Nortel in 2011. Network World Over time, prices per individual IPv4 address have climbed into the tens of dollars, reflecting increasing demand and the dwindling supply. Many enterprises, internet service providers and network operators now regard substantial IPv4 holdings as intangible assets that can be sold or monetised, rather than mere operational resources.

Mechanisms of the IPv4 Market and Asset Classification
The modern IPv4 market has several mechanisms. Organisations with surplus address space can transfer or sell blocks to those in need, often facilitated by specialised brokers and marketplace platforms. Some RIRs have formalised transfer listing services to support transparency and legitimacy. Network World Leases are another emerging feature, where holders of IPv4 inventory generate recurring revenue by leasing addresses to companies requiring temporary or additional network resources.
From a financial perspective, IPv4 addresses increasingly resemble other asset classes. They are traded, held for value appreciation and considered in strategic capital planning. Advisors recommend that enterprises audit their IPv4 holdings and quantify them alongside other digital assets. Investors and network operators are attentive to pricing trends, regional policy variations and the competitive dynamics of these digital assets. Some securitisation efforts have even arisen, where IPv4 addresses back financial instruments issued by providers.
Challenges and Future Trends
The rise of IPv4 markets raises important questions. Is treating IPv4 space as an asset class a sustainable long‑term model when the underlying scarcity is artificial, created by the legacy protocol’s limits? Regional differences in transfer rules, such as needs‑based justification requirements in some RIRs but not others, can slow transactions and complicate valuation. Moreover, the world’s gradual transition to IPv6 — a protocol offering a vastly larger address space — could diminish demand for IPv4 over time, even though IPv6 adoption remains uneven in many sectors.
Regulators and internet governance bodies also face scrutiny about whether current policies appropriately balance technical networking needs with emerging financial dynamics. Some analysts question if the commoditisation of IPv4 space could lead to speculative behaviours or hinder efficient allocation to organisations that require addresses for legitimate operational expansion. Others argue that an active market creates incentives for efficient reuse of underutilised resources.
In sum, the IPv4 address market today sits at the intersection of networking necessity and financial asset behaviour. As digital infrastructure continues to underpin economic activity worldwide, the classification of IPv4 addresses as assets highlights how a once‑mundane technical resource can acquire economic significance — but not without debate about long‑term implications.
