Likely issued from LACNIC-controlled inventory
No transfer record matches. LACNIC's statistics show it available on 2017-05-03 and allocated (dated 2017-05-04) on 2017-05-04. The tracker saw this range released from hold on 2017-05-03 (190.123.192.0/22), so it appears to have been issued again from LACNIC's pool. Another change to this range was reported the day before or after (2017-05-03: Released 190.123.192.0/22), so the before-and-after statistics may include it.

LACNIC's statistics now list it as 'available'; reissue not confirmed
LACNIC's statistics show it reserved on 2017-05-02 and available on 2017-05-03. LACNIC moved it from its reserved (held) records to the status it calls 'available'. That is LACNIC's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2017-05-04: Added 190.123.192.0/22), so the before-and-after statistics may include it.

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.
