IPv4 Supplies On The Brink Of Exhaustion

The world is on the brink of running out of IPv4 addresses after the Internet Assigned Numbers Authority (IANA) assigned four IPv4 blocks to two different registries, leaving only 7 in the global pool.

The organisation has warned that all IPv4 address will run out next year, urging businesses to adopt the new IPv6 protocol.

Two of the four blocks have been assigned to the American Registry for Internet Numbers, with RIPE NCC, which handles domain names in Middle East and Asia, being assigned the other two.

The authority has assigned a total of 19 blocks this year and with seven blocks remaining, it expects that the blocks will run out sooner than expected.

Axel Pawlik, the managing director of RIPE NCC, said in a statement: “The current numbers say that will happen at the end of 2011, but I think there’s a gut feeling everywhere that with the acceleration in growth, that might move forward. It’s a matter of a few big requests to us, and that will happen a bit quicker.”
