Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it assigned (dated 2021-04-06) on 2026-10-16 and reserved on 2026-10-17. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, but its statistics have released returned IPv4 space a year after the removal or later since 2014, so the tracker estimates the hold ends on 2027-10-16. 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 2021-04-06 and assigned (dated 2021-04-06) on 2021-04-07. It moved from APNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by APNIC.
