No transfer record matches. APNIC's statistics show it available on 2026-10-19 and allocated (dated 2026-10-19) on 2026-10-20. The tracker saw this range released from hold on 2026-10-18 (AS150117), so it appears to have been issued again from APNIC's pool. Another change to this range was reported the day before or after (2026-10-18: Released AS150117), so the before-and-after statistics may include it.

APNIC's statistics now list it as 'available'; reissue not confirmed
APNIC's statistics show it reserved on 2026-10-18 and available on 2026-10-19. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2025-10-17, 366 days earlier. That is APNIC's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2026-10-19: Added AS150117), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2026-10-17. 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 2022-07-08) on 2025-10-17 and available on 2025-10-18. 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 2026-10-17. That is what APNIC has done, not a rule it states. This does not confirm availability.
