No transfer record matches. APNIC's statistics show it available on 2019-05-03 and allocated (dated 2019-05-03) on 2019-05-04. The tracker saw this range removed from registration on 2018-05-02 (AS135124), so it appears to have been issued again from APNIC's pool.

Hold estimate
Estimated hold end 2019-05-02. 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 2016-02-24) on 2018-05-02 and available on 2018-05-03. 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 2019-05-02. 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 2016-02-24 and allocated (dated 2016-02-24) on 2016-02-25. 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.
