Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it assigned (dated 2024-06-17) on 2026-10-26 and reserved on 2026-10-27. 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 2027-10-26. 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 reserved on 2026-01-05 and assigned (dated 2024-06-17) on 2026-01-06. The tracker saw it removed from registration on 2025-10-20 (77 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.

Likely issued from APNIC-controlled inventory

No transfer record matches. APNIC's statistics show it available on 2024-06-17 and assigned (dated 2024-06-17) on 2024-06-18. The tracker saw this range released from hold on 2020-07-10 (160.22.0.0/16), so it appears to have been issued again from APNIC's pool.
