LACNIC's statistics now list it as 'available'; reissue not confirmed
LACNIC's statistics show it reserved on 2020-03-17 and available on 2020-03-18. LACNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2019-06-24, 268 days earlier. That is LACNIC's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Removed from active registration. The tracker found it by comparing LACNIC's daily statistics. LACNIC's statistics show it assigned (dated 2005-11-18) on 2019-06-23 and reserved on 2019-06-24. Public sources do not distinguish a voluntary return, revocation, or reclamation. LACNIC's current hold for IPv4 space applies to removals from 2020-03-01 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.
