Likely issued from LACNIC-controlled inventory

No transfer record matches. LACNIC's statistics show it reserved on 2017-12-18 and allocated (dated 2017-12-19) on 2017-12-19. The tracker saw this range released from hold on 2017-12-15 (45.228.12.0/22), so it appears to have been issued again from LACNIC's pool.

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.
