Likely issued from LACNIC-controlled inventory
No transfer record matches. LACNIC's statistics show it available on 2018-02-22 and assigned (dated 2018-02-23) on 2018-02-23. The tracker saw this range released from hold on 2018-02-22 (45.229.150.0/24), so it appears to have been issued again from LACNIC's pool. Another change to this range was reported the day before or after (2018-02-22: Released 45.229.150.0/24), so the before-and-after statistics may include it.

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.
