No transfer record matches. ARIN's statistics show it reserved on 2021-04-05 and allocated (dated 2021-04-06) on 2021-04-07. The tracker saw this range removed from registration on 2019-05-06 (172.82.0.0/17), so it appears to have been issued again from ARIN's pool.

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.
