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.
