\"IPv4<\/a>The American Registry for Internet Numbers (ARIN<\/a>) announced (10-20-2010) that Interop<\/a> returned its unneeded Internet Protocol version 4 (IPv4) address space. The ARIN Press Release<\/a> explains that Interop was originally allocated a \/8 before ARIN’s existence and the availability of smaller address blocks.<\/p>\n

Another press release<\/a> indicates that Interop founder Dan Lynch acquired the addresses block to allow for unfettered Interoperability Testing between TCP\/IP equipment vendors in the formative years of the Internet. Interop will continue to use a small part of the original grant to continue Interop’s 25-year mission to foster industry-wide interoperability while returning the rest of the address block to ARIN for the greater good of the Internet community. The organization recently realized it was only using a small part of its address block and that returning the rest to ARIN would be for the greater good of the Internet community.<\/p>\n

\"\"<\/a>ARIN will accept the returned space and not reissue it for a short period, per existing operational procedure. After the hold period, ARIN will follow global policy at that time and return it to the global free pool or distribute the space to those organizations in the ARIN region with documented need, as appropriate.<\/p>\n

With less than 5% of the IPv4 address space left in the global free pool, ARIN warns that Interop’s return will not significantly extend the life of IPv4. ARIN continues to emphasize the need for all Internet stakeholders to adopt the next generation of Internet Protocol, IPv6.<\/p>\n

As the original poster<\/a> at Slashdot<\/a> points out, if any of the other IPv4 \/8 address holders return their unused addresses, the IPv4 exhaustion date would be pushed back even further. I wonder what some of these companies plan on doing with all of these IP addresses? <\/em><\/p>\n
