Likely issued from LACNIC-controlled inventory
No transfer record matches. LACNIC's statistics show it available on 2015-10-20 and assigned (dated 2015-10-21) on 2015-10-21. The tracker saw this range released from hold on 2015-10-08 (200.9.186.0/24), so it appears to have been issued again from LACNIC's pool.

LACNIC's statistics now list it as 'available'; reissue not confirmed
LACNIC's statistics show it reserved on 2015-10-07 and available on 2015-10-08. LACNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2013-03-25, 927 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 1993-11-26) on 2013-03-24 and available on 2013-03-25. 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.

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.
