ARIN recognizes Interop for return of more than 99% of 45/8 address block

Wed Oct 20 16:29:02 UTC 2010

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.

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.

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.
