IPv4 addresses were generally free through Regional Internet Registries (RIRs) — such as American Registry for Internet Numbers (ARIN). By 2001 there was a shortage of IPv4 space ,and ARIN confirmed in 2015 that they will not assign any more free space. ARIN will no longer assign IPv4 addresses unless customers meet very specific requirements. Basically, IPv4 addresses are only available through trading or transfers through secondary markets.
Even with the free availability running out, IPv4 is still the most used Internet Protocol used to connect devices with a 32-bit address. The rollout of IPv6 while almost a limitless supply of addresses is a slow-moving process because it is not entirely compatible with all things IPv4. Migration and upgrades can be costly for many organizations. Significant upgrades to infrastructure, routers, switches, firewalls, or trying to run IPv4 and IPv6 concurrently, can be expensive, and many have chosen to make the upgrade over time as a long-term project instead of making the leap all at once.
Many institutions or companies have sat on large quantities of IPv4 addresses. Millions of these addresses have and will never be used, which creates a great secondary market for interested parties. The selling of IPv4 addresses while currently in abundance, will become more scarce over the foreseable future.
How to buy an IPv4 address?
Buying IPv4 addresses can be risky and complicated for the less experienced. This is especially true since there are policies and rules through ICANN (The Internet Corporation for Assigned Names and Numbers) and American Registry for the Internet Numbers (ARIN) that need to be followed when transferring the addresses. There are specific requirements that must be met before you can buy IPv4 addresses. Some regions require pre-approval through Regional Internet Registry (RIR).
Five Steps to buying IPv4 Addresses
- Pre-approval. – Present ARIN, RIPE and/or APNIC with requirements for needing extra address space. Provide information on your current address usage, and expected growth rates.
- Find a partner. Find a partner, like us, that has best relationships and makes you feel like they really care.
- Price and payment settlement. Prices vary – generally, based on region, size and if they look clean.
- IPv4 transfer. Many transfers use an ’Escrow’ service, to act as a trusted third-party. After verified payment is received, the seller transfers the prefixes to the the registry account. They will then validate the pre-approval and set the transfer fee based on the size of the IPv4 block. The addresses are now yours.
- Update ARIN, Whois, DNS records, Firewalls, border ACLs, BGP and Geo-IP services.
