ARIN's statistics show it reserved on 2024-04-01 and allocated (dated 2024-04-02), available, reserved on 2024-04-03. ARIN removed its own pool record for this range as part of issuing it: the same report adds 130.51.112.0-130.51.115.255, 130.51.116.0-130.51.119.255, 130.51.121.0-130.51.121.255, 130.51.122.0-130.51.122.255 and 2 more. The issuance is explained on those lines. Another change to this range was reported the day before or after (2024-04-03: Add 130.51.127.0-130.51.127.255), 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.
