Hold estimate

Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 2008-11-14) on 2019-03-21 and available on 2019-03-22. 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 2020-03-21. 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 2008-11-14 and allocated (dated 2008-11-14) on 2008-11-15. 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.

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.
