Likely issued from APNIC-controlled inventory
No transfer record matches. APNIC's statistics show it available on 2026-03-05 and allocated (dated 2026-03-05) on 2026-03-06. The tracker saw this range released from hold on 2026-03-04 (AS146992), so it appears to have been issued again from APNIC's pool. Another change to this range was reported the day before or after (2026-03-04: Released AS146992), 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 2026-03-04 and available on 2026-03-05. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2025-03-03, 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 (2026-03-05: Added AS146992), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2026-03-03. 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 allocated (dated 2021-08-30) on 2025-03-03 and available on 2025-03-04. 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 2026-03-03. 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 available on 2021-08-30 and allocated (dated 2021-08-30) on 2021-08-31. It moved from APNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by APNIC.

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.
