The Internet Assigned Numbers Authority (IANA) has released new IPv4 address space to the five Regional Internet Registries worldwide. Each was given roughly 1.05 million addresses. The addresses are from a pool of leftover and returned IPv4 address blocks from which IANA can make periodic allocations to the regional registries, which manage IP address allocation and registration in different parts of the world. Despite the release of IPv4 addresses, IANA emphasizes that their overall number is dwindling and that equipment makers, service providers, and others need to adopt IPv6, which provides many more addresses, as soon as possible.
