No transfer record matches. LACNIC's statistics show it not listed on 2019-05-12 and allocated (dated 1989-03-31) on 2019-05-13. It wasn't in LACNIC's statistics before, so it wasn't LACNIC's unissued inventory; it may have come from another registry in a transfer not yet in the log.

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 1989-03-31) on 2019-05-07 and not listed on 2019-05-08. Being gone from LACNIC's statistics entirely can also mean it moved to another registry. 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.
