No effect on LACNIC applicant inventory
No transfer record matches. LACNIC's statistics show it reserved on 2026-05-03 and allocated (dated 2023-11-08) on 2026-05-04. The tracker saw it removed from registration on 2026-04-14 (20 days earlier), and it is back with the same holder record it had before, so it went back to its previous holder rather than to a new one: most likely a suspension lifted, a reinstatement or a correction.

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 2023-11-08) on 2026-04-13 and reserved on 2026-04-14. 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.
