No transfer record matches. APNIC's statistics show it available on 2022-08-05 and allocated (dated 2022-08-05) on 2022-08-06. The tracker saw this range removed from registration on 2021-08-04 (AS137535), 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 2021-05-26) on 2021-08-04 and available on 2021-08-05. 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 2022-08-04. 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 (2018-03-27: Added AS137535), so the before-and-after statistics may include it.

No transfer record matches. APNIC's statistics show it available on 2018-03-27 and allocated (dated 2018-03-27) on 2018-03-28. 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 (2018-03-28: Removed AS137535), 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.
