Hold estimate
Estimated hold end 2026-11-04. 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 2019-08-21) on 2026-05-03 and reserved on 2026-05-04. 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 2026-11-04. This does not confirm availability.

Likely issued from LACNIC-controlled inventory

No transfer record matches. LACNIC's statistics show it reserved on 2019-08-20 and allocated (dated 2019-08-21) on 2019-08-21. The tracker saw this range released from hold on 2017-04-05 (45.160.0.0/11), so it appears to have been issued again from LACNIC's pool.

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.
