No effect on APNIC applicant inventory
No transfer record matches. APNIC's statistics show it available on 2016-10-07 and allocated (dated 2011-04-29) on 2016-10-08. The tracker saw it removed from registration on 2016-07-04 (95 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.

Hold estimate
Estimated hold end 2017-07-04. Possible reissue candidate after this date; not confirmed available.
Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 2011-04-29) on 2016-07-04 and available on 2016-07-05. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, but its statistics have released returned ASNs a year after the removal or later since 2014, so the tracker estimates the hold ends on 2017-07-04. That is what APNIC has done, not a rule it states. This does not confirm availability.

No transfer record matches. APNIC's statistics show it available on 2011-04-29 and allocated (dated 2011-04-29) on 2011-04-30. It moved from APNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by APNIC.

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.
