Understanding the IPv4 Address Market
IANA Exhaustion
Global IPv4 pool exhausted in 2011
No new allocations possible from RIRs
Rising Demand
Prices have increased 300%+ since 2015
Driven by cloud, IoT, and 5G growth
4.3B Total Addresses
IPv4 uses 32-bit addressing
Finite supply with growing demand
Mature Market
Regulated secondary market ecosystem
Governed by ARIN, RIPE, APNIC
The IPv4 address market emerged after the Internet Assigned Numbers Authority (IANA) exhausted the global pool of IPv4 addresses in 2011. While IPv6 adoption has been growing, the vast majority of internet infrastructure still relies on IPv4, creating sustained demand for these finite resources.
Regional Internet Registries (RIRs) — including ARIN (North America), RIPE NCC (Europe), and APNIC (Asia-Pacific) — allocated their remaining IPv4 address pools shortly after IANA exhaustion. This created a secondary market where organizations buy, sell, and lease IPv4 address blocks from existing holders.
Today, the IPv4 market is a mature, regulated ecosystem. Prices are influenced by block size, registry region, IP reputation, and market demand. Organizations need IPv4 addresses for expanding network infrastructure, launching new services, cloud deployments, and maintaining operations that haven't yet transitioned to IPv6.
Why IPv4 Addresses Are Scarce
IPv4 uses 32-bit addresses, providing approximately 4.3 billion unique addresses. With billions of devices now connected to the internet, this pool was exhausted in 2011. New allocations are no longer possible from RIRs, making the secondary market the only source for additional IPv4 space.
IPv4 vs IPv6
While IPv6 offers a virtually unlimited address space (128-bit), adoption remains incomplete. Many legacy systems, applications, and networks still require IPv4 connectivity. IPv4 Depot helps organizations bridge this gap with both IPv4 and IPv6 solutions.
