IANA allocates recovered IPv4 addresses to RIRs

1 Sep 2017

These allocations have been made from IANA’s recovered IPv4 pool, in line with a global policy adopted in May 2012. The recovered IPv4 pool which contains fragments left over in the IANA inventory after the last /8s of the IPv4 space are delegated to the RIRs, and IPv4 addresses returned to IANA by any means.
