ARIN's statistics show it reserved on 2025-10-05 and allocated (dated 2025-10-06) on 2025-10-07. ARIN removed its own pool record for this range as part of issuing it: the same report adds 192.12.250.0-192.12.250.255. 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.
