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 2023-04-24) on 2025-11-16 and reserved on 2025-11-17. 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.

Likely issued from LACNIC-controlled inventory
No transfer record matches. LACNIC's statistics show it available on 2023-04-23 and allocated (dated 2023-04-24) on 2023-04-24. It moved from LACNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by LACNIC.

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.
