ARIN's statistics show it reserved on 2021-03-30 and allocated (dated 2021-03-31), available, reserved on 2021-04-01. ARIN removed its own pool record for this range as part of issuing it: the same report adds 45.42.204.0-45.42.204.255, 45.42.206.0-45.42.206.255. The issuance is explained on those lines. Another change to this range was reported the day before or after (2021-04-01: Add 45.42.208.0-45.42.211.255; 2021-04-01: Add 45.42.213.0-45.42.213.255; 2021-04-01: Add 45.42.216.0-45.42.219.255), 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.
