No transfer record matches. LACNIC's statistics show it reserved on 2026-10-13 and allocated (dated 2026-10-14) on 2026-10-14. The tracker saw this range released from hold on 2026-10-07 (164.163.243.0/24), so it appears to have been issued again from LACNIC's pool.

LACNIC's statistics now list it as 'available'; reissue not confirmed

LACNIC's statistics show it reserved on 2026-10-06 and available on 2026-10-07. LACNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2026-04-22, 168 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 2026-10-22. 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 assigned (dated 2017-08-10) on 2026-04-21 and reserved on 2026-04-22. 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 2026-10-22. This does not confirm availability.

No transfer record matches. LACNIC's statistics show it reserved on 2017-08-09 and assigned (dated 2017-08-10) on 2017-08-10. It moved from LACNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by LACNIC.
