Every change the tracker has found, newest first. It covers ARIN from 2008-12-01, the RIPE NCC from 2010-04-23, APNIC from 2008-02-15, LACNIC from 2012-06-29 and AFRINIC from 2012-10-03.

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 2012-03-14) on 2012-05-20 and reserved on 2012-05-21. 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.

Likely issued from RIPE NCC-controlled inventory

No transfer record matches. The RIPE NCC's statistics show it reserved on 2012-03-13 and assigned (dated 2012-03-14) on 2012-03-14. The tracker saw this range removed from registration on 2010-12-17 (139.28.0.0/16), so it appears to have been issued again from the RIPE NCC's pool.

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 1984-01-01) on 2010-12-16 and available on 2010-12-17. 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.

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.
