LACNIC's statistics now list it as 'available'; reissue not confirmed
LACNIC's statistics show it reserved on 2017-04-04 and available on 2017-04-05. LACNIC moved it from its reserved (held) records to the status it calls 'available'. That is LACNIC's own label: whether and when it is reissued is not confirmed.

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 2011-01-27 (128.201.0.0/16), 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 1999-07-06) on 2011-01-26 and available on 2011-01-27. 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.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.
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.
