Interested to know how this will show in the IANA v4 address space registry. Will 045/8 soon appear as belonging to ARIN, since it is now not Interop's? Also makes me wonder if there are historical versions of this registry available. If reclamation of large blocks such as this becomes commonplace, will many of the legacy allocations simply become footnotes? (In the registry document, as well as in history?) -S.

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.
