No transfer record matches. APNIC's statistics show it available on 2021-04-15 and allocated (dated 2021-04-15) on 2021-04-16. The tracker saw this range removed from registration on 2020-04-15 (AS137213), so it appears to have been issued again from APNIC's pool.

Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 2020-03-09) on 2020-04-15 and available on 2020-04-16. 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 2021-04-15. That is what APNIC has done, not a rule it states. 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.
