No transfer record matches. The RIPE NCC's statistics show it not listed on 2011-04-04 and assigned (dated 2011-04-04) on 2011-04-05. It wasn't in the RIPE NCC's statistics before, so it wasn't the RIPE NCC's unissued inventory; it may have come from another registry in a transfer not yet in the log.

Possible future reissue candidate after hold
Removed from active registration. The tracker found it by comparing the RIPE NCC's daily statistics. The RIPE NCC's statistics show it assigned (dated 2006-05-05) on 2010-12-15 and available on 2010-12-16. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC's current hold for IPv4 space applies to removals from 2014-03-26 on, and this one came earlier, so the tracker gives no estimate. This does not confirm availability.

No transfer log has a transfer of any part of this IPv4 range.
RDAP lookups
Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
