LACNIC's statistics show it reserved on 2025-05-13 and available on 2025-05-14. LACNIC moved it from its reserved (held) records to the status it calls 'available'. 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 2025-02-08. 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 2017-03-15) on 2024-08-07 and reserved on 2024-08-08. 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 2025-02-08. This does not confirm availability.

No transfer record matches. LACNIC's statistics show it reserved on 2017-03-14 and allocated (dated 2017-03-15) on 2017-03-15. 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.
