Inventory
No effect on APNIC applicant inventory
No transfer record matches. APNIC's statistics show it available on 2011-04-12 and allocated (dated 2011-04-12) on 2011-04-13. The tracker saw it removed from registration on 2011-03-28 (15 days earlier), and it is back with the same holder record it had before, so it went back to its previous holder rather than to a new one: most likely a suspension lifted, a reinstatement or a correction.

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.
