ARIN today recognizes Interop, an organization with a long-standing presence in the Internet industry, for returning 
its unneeded Internet Protocol version 4 (IPv4) address space.

Interop was originally allocated a /8 before ARIN's existence and the availability of smaller-sized address blocks. The 
organization recently realized it was only using a small portion of its address block and that returning the remainder 
to ARIN would be for the greater good of the Internet community.

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.

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.
