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 2013-01-07) on 2013-01-29 and reserved on 2013-01-30. 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.

Inventory
Likely issued from RIPE NCC-controlled inventory
No transfer record matches. The RIPE NCC's statistics show it reserved on 2013-01-06 and assigned (dated 2013-01-07) on 2013-01-07. The tracker saw this range removed from registration on 2013-01-02 (151.217.0.0/16), so it appears to have been issued again from the RIPE NCC's pool.

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.
