APNIC's statistics now list it as 'available'; reissue not confirmed
APNIC's statistics show it reserved on 2025-02-05 and available on 2025-02-06. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2022-09-16, 873 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 2023-09-16. 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 2017-01-11) on 2022-09-16 and reserved on 2022-09-17. 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 2023-09-16. 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 2021-08-30 and allocated (dated 2017-01-11) on 2021-08-31. The tracker saw it removed from registration on 2021-05-12 (110 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.

Likely issued from APNIC-controlled inventory
No transfer record matches. APNIC's statistics show it available on 2017-01-11 and allocated (dated 2017-01-11) on 2017-01-12. It moved from APNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by APNIC.

No transfer log has a transfer of any part of this IPv4 range.
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.
