No transfer record matches. APNIC's statistics show it reserved on 2023-01-27 and assigned (dated 2011-02-11) on 2023-01-28. The new registration isn't dated near that day, so the tracker can't tell whether this is a new issuance.

Possible future reissue candidate after hold
Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it assigned (dated 1988-11-22) on 2011-02-11 and not listed on 2011-02-12. Being gone from APNIC's statistics entirely can also mean it moved to another registry. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, and its statistics show a steady one (a year) only for removals from 2014-07-01 on; this one came earlier, so the tracker gives no estimate. This does not confirm availability.

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.
