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

APNIC's statistics show it reserved on 2021-06-30 and available on 2021-07-01. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2020-06-25, 370 days earlier. That is APNIC's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2021-06-25. 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 2010-08-10) on 2020-06-25 and reserved on 2020-06-26. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, but its statistics have released returned IPv4 space a year after the removal or later since 2014, so the tracker estimates the hold ends on 2021-06-25. That is what APNIC has done, not a rule it states. This does not confirm availability.

No effect on APNIC applicant inventory

No transfer record matches. APNIC's statistics show it reserved on 2015-12-14 and allocated (dated 2010-08-10) on 2015-12-15. The tracker saw it removed from registration on 2015-11-10 (34 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.

No transfer record matches. APNIC's statistics show it not listed on 2010-08-10 and allocated (dated 2010-08-10) on 2010-08-11. It wasn't in APNIC's statistics before, so it wasn't APNIC's unissued inventory; it may have come from another registry in a transfer not yet in the log.

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 2010-05-11) on 2010-07-28 and not listed on 2010-07-29. 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.
