Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it not issued on 2011-07-28 and allocated (dated 2011-07-29) on 2011-07-30. (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.
