Hold estimate
Estimated hold end 2027-10-12. Possible reissue candidate after this date; not confirmed available.
Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it assigned (dated 2026-10-05) on 2026-10-12 and available on 2026-10-13. 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 2027-10-12. That is what APNIC has done, not a rule it states. This does not confirm availability.

Likely issued from APNIC-controlled inventory
No transfer record matches. APNIC's statistics show it available on 2026-10-06 and assigned (dated 2026-10-05) on 2026-10-07. The tracker saw this range released from hold on 2020-08-03 (163.61.0.0/16), so it appears to have been issued again from APNIC's pool.
