Hold estimate
Estimated hold end 2024-11-30. 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 2023-11-29) on 2023-11-30 and available on 2023-12-01. 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 2024-11-30. That is what APNIC has done, not a rule it states. This does not confirm availability. Another change to this range was reported the day before or after (2023-11-29: Added AS152147-AS152148), so the before-and-after statistics may include it.

No transfer record matches. APNIC's statistics show it available on 2023-11-29 and allocated (dated 2023-11-29) on 2023-11-30. It moved from APNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by APNIC. Another change to this range was reported the day before or after (2023-11-30: Removed AS152147-AS152148), so the before-and-after statistics may include it.

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.
