ICANN Digs, Finds More Space On The Net

February 10, 2008 | 11:51 AM

The Internet Corporation for Assigned Names and Numbers has found a little breathing room in the existing address space known as IPv4 with its recovery of a block of 16 million addresses. The IP addresses recovered were once used to connect older protocol packet-data networks with the fledgling Internet, according to a press release.

A small percentage of the addresses had been assigned, most more than 15 years ago. The assignments were so old that finding people who knew about them was a lengthy process. Nearly 50 organizations worked cooperatively with ICANN staff last year to confirm that the 984 registrations were no longer in use.

While the reclamation of the IPv4 space is a temporary fix, Barbara Roseman of ICANN's Internet Assigned Numbers Authority, said "the real and lasting solution is the technical move to IPv6 -- the protocol that will make 340 trillion trillion trillion unique IP addresses available."
