Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it reserved on 2014-08-10 and allocated (dated 2014-08-11) on 2014-08-12. 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.
