No effect on APNIC applicant inventory

No transfer record matches. APNIC's statistics show it reserved on 2026-10-29 and allocated (dated 1992-10-22) on 2026-10-30. The tracker saw it removed from registration on 2026-04-27 (185 days earlier), and it is back with the same holder record it had before, so it went back to its previous holder rather than to a new one: most likely a suspension lifted, a reinstatement or a correction.

Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 1992-10-22) on 2026-04-27 and reserved on 2026-04-28. 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 2027-04-27. That is what APNIC has done, not a rule it states. This does not confirm availability.
