No transfer record matches. ARIN's statistics show it not issued on 2012-01-30 and allocated (dated 2012-01-31) on 2012-02-01. (Until 2013-03-05, ARIN's statistics list only what's issued.) 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.
