SAN FRANCISCO, Oct. 20 /PRNewswire/ -- Interop®, produced by UBM TechWeb, today announced that it will release a portion of its Internet Protocol version 4 (IPv4) address block (called a "/8" or "slash-eight") , to the American Registry for Internet Numbers (ARIN) in an effort to drive Internet Protocol version 6 (IPv6) adoption. This significant move demonstrates Interop's commitment to driving the adoption of IPv6 in the critical last days before IPv4 depletion. The event is currently taking place at the Javits Convention Center until October 22.  For more information visit:

"IPv4 depletion is one of the most critical issues facing the Internet today," said Lenny Heymann, Interop General Manager. "Interop is pleased to return our /8 IPv4 addresses in an effort to sustain the life of IPv4 and drive in IPv6 adoption. This week we'll be looking at the tremendous changes happening in the business technology landscape, including this new IP standard, and will dive deep into what this means, the challenges it brings and present real-world solutions for the adoption of IPv6."

"ARIN thanks Interop for returning its IPv4 addresses," said John Curran, President and CEO of ARIN. "Interop, an organization with a long-standing presence in the industry, is setting a great example for other organizations with excess IPv4 address space for the betterment of the community and health of the Internet, and to progress the migration to IPv6. Because we are so close to IPv4 depletion, we are especially thrilled with Interop's return."

Industry visionary Dan Lynch, the founder of Interop, 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 portion of the original grant to continue Interop's 25-year mission to foster industry-wide interoperability, while returning the remainder of the address block to ARIN for the greater good of the Internet community. ARIN will accept Interop's /8 and hold 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.
