LACNIC's statistics now list it as 'available'; reissue not confirmed
LACNIC's statistics show it reserved on 2024-11-04 and available on 2024-11-05. LACNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2024-05-13, 176 days earlier. That is LACNIC's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2024-11-13. Possible reissue candidate after this date; not confirmed available.
Removed from active registration. The tracker found it by comparing LACNIC's daily statistics. LACNIC's statistics show it allocated (dated 2012-10-23) on 2024-05-12 and reserved on 2024-05-13. Public sources do not distinguish a voluntary return, revocation, or reclamation. LACNIC holds returned, revoked and reclaimed IPv4 space for 6 calendar months before reissuing it, so the estimated hold end is 2024-11-13. 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.
