No effect on LACNIC applicant inventory
No transfer record matches. LACNIC's statistics show it reserved on 2024-05-21 and allocated (dated 2021-12-22) on 2024-05-22. The tracker saw it removed from registration on 2024-05-16 (6 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 2024-11-16. 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 2021-12-22) on 2024-05-15 and reserved on 2024-05-16. 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 2024-11-16. This does not confirm availability.

Likely issued from LACNIC-controlled inventory
No transfer record matches. LACNIC's statistics show it reserved on 2021-12-21 and allocated (dated 2021-12-22) on 2021-12-22. The tracker saw this range removed from registration on 2021-06-07 (181.224.192.0/21), so it appears to have been issued again from LACNIC's pool.

Classification history for this change (4 versions)
Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.
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.
