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

APNIC's statistics show it reserved on 2026-11-04 and available on 2026-11-05. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2025-11-03, 366 days earlier. That is APNIC's own label: whether and when it is reissued is not confirmed.

Hold estimate
Estimated hold end 2026-11-03. 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 assigned (dated 2008-11-07) on 2025-11-03 and reserved on 2025-11-04. 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 2026-11-03. 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 not listed on 2008-11-07 and assigned (dated 2008-11-07) on 2008-11-08. 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.
