No transfer record matches. APNIC's statistics show it available on 2026-11-12 and assigned (dated 2026-11-12) on 2026-11-13. The tracker saw this range removed from registration on 2023-02-23 (203.18.149.0/24), 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 assigned (dated 2009-02-19) on 2023-02-23 and available on 2023-02-24. 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 2024-02-23. That is what APNIC has done, not a rule it states. This does not confirm availability.
