No transfer record matches. LACNIC's statistics show it reserved on 2021-12-13 and allocated (dated 2021-12-14) on 2021-12-14. The tracker saw this range removed from registration on 2021-06-07 (181.233.0.0/18), 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.
