APNIC's statistics now list it as 'available'; reissue not confirmed

APNIC's statistics show it reserved on 2015-10-28 and available on 2015-10-29. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2012-12-11, 1051 days earlier. That is APNIC's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold

Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 2006-10-23) on 2012-12-11 and reserved on 2012-12-12. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, and its statistics show a steady one (a year) only for removals from 2014-07-01 on; this one came earlier, so the tracker gives no estimate. This does not confirm availability.

No effect on APNIC applicant inventory

No transfer record matches. APNIC's statistics show it available on 2011-02-01 and allocated (dated 2006-10-23) on 2011-02-02. The tracker saw it removed from registration on 2010-12-01 (62 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.

Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 2006-10-23) on 2010-12-01 and not listed on 2010-12-02. Being gone from APNIC's statistics entirely can also mean it moved to another registry. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, and its statistics show a steady one (a year) only for removals from 2014-07-01 on; this one came earlier, so the tracker gives no estimate. This does not confirm availability.

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.
