No transfer record matches. LACNIC's statistics show it reserved on 2023-12-07 and allocated (dated 2018-04-11) on 2023-12-08. The tracker saw it removed from registration on 2023-11-27 (11 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.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2024-05-27. 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 2018-04-11) on 2023-11-26 and reserved on 2023-11-27. 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 2024-05-27. This does not confirm availability.

Likely issued from LACNIC-controlled inventory
No transfer record matches. LACNIC's statistics show it reserved on 2018-04-10 and allocated (dated 2018-04-11) on 2018-04-11. The tracker saw this range released from hold on 2017-04-05 (45.224.0.0/12), so it appears to have been issued again from LACNIC's pool.

No transfer log has a transfer of any part of this IPv4 range.
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.
