No transfer record matches. ARIN's statistics show it reserved on 2020-03-26 and assigned (dated 2020-03-27) on 2020-03-28. The tracker saw this range released from hold on 2020-03-26 (64.66.240.0-64.66.255.255), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2020-03-26: Remove 64.66.240.0-64.66.255.255), so the before-and-after statistics may include it.

ARIN's statistics show it reserved on 2020-03-26 and assigned (dated 2020-03-27) on 2020-03-28. ARIN removed its own pool record for this range as part of issuing it: the same report adds 64.66.252.0-64.66.252.255. The issuance is explained on that line. Another change to this range was reported the day before or after (2020-03-26: Remove 64.66.240.0-64.66.255.255), 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.
