No effect on LACNIC applicant inventory

No transfer record matches. LACNIC's statistics show it reserved on 2026-04-21 and allocated (dated 2020-08-25) on 2026-04-22. The tracker saw it removed from registration on 2026-04-14 (8 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.

Removed from active registration. The tracker found it by comparing LACNIC's daily statistics. LACNIC's statistics show it allocated (dated 2020-08-25) on 2026-04-13 and reserved on 2026-04-14. 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 2026-10-14. This does not confirm availability.

Likely issued from LACNIC-controlled inventory

No transfer record matches. LACNIC's statistics show it reserved on 2020-08-24 and allocated (dated 2020-08-25) on 2020-08-25. The tracker saw this range released from hold on 2020-03-23 (190.12.128.0/19), so it appears to have been issued again from LACNIC's pool.
