Likely issued from APNIC-controlled inventory
No transfer record matches. APNIC's statistics show it available on 2011-03-30 and allocated (dated 2011-03-30) on 2011-03-31. It moved from APNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by APNIC.

ARIN-Issued says "Remove", but ARIN's statistics show it not issued on 2009-07-12 and not issued on 2009-07-14. (Until 2013-03-05, ARIN's statistics list only what's issued.) The registry's pool records from that time aren't public, so the tracker can't tell what was removed.

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.
