Hold estimate
Estimated hold end 2027-10-26. 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 allocated (dated 2013-09-27) 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 ASNs 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.
