Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it reserved on 2020-02-02 and allocated (dated 2020-02-03) on 2020-02-04. The tracker saw this range released from hold on 2020-01-17 (158.51.184.0-158.51.235.255), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2020-02-02 and allocated (dated 2020-02-03) on 2020-02-04. ARIN removed its own pool record for this range as part of issuing it: the same report adds 158.51.232.0-158.51.235.255. The issuance is explained on that line.

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.
