No transfer record matches. ARIN's statistics show it available on 2020-02-24 and allocated (dated 2020-02-25) on 2020-02-26. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

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.
