No transfer record matches. LACNIC's statistics show it available on 2019-08-11 and allocated (dated 2019-08-12) on 2019-08-12. The tracker saw this range released from hold on 2018-05-23 (AS11431), 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 2018-05-22 and available on 2018-05-23. LACNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2015-06-23, 1065 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 allocated (dated 1999-11-17) on 2015-06-22 and reserved on 2015-06-23. Public sources do not distinguish a voluntary return, revocation, or reclamation. LACNIC publishes no fixed period for which it holds returned ASNs before reissuing them, 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.
