APNIC's statistics now list it as 'available'; reissue not confirmed
APNIC's statistics show it reserved on 2026-10-06 and available on 2026-10-07. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2026-10-05, 1 days earlier. That is APNIC's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2026-10-05: Removed 163.52.192.0/24), so the before-and-after statistics may include it.

Hold estimate
Estimated hold end 2027-10-05. 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 2026-09-16) on 2026-10-05 and reserved on 2026-10-06. 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 2027-10-05. That is what APNIC has done, not a rule it states. This does not confirm availability. Another change to this range was reported the day before or after (2026-10-06: Released 163.52.192.0/24), so the before-and-after statistics may include it.

Likely issued from APNIC-controlled inventory
No transfer record matches. APNIC's statistics show it available on 2026-09-16 and allocated (dated 2026-09-16) on 2026-09-17. The tracker saw this range released from hold on 2021-11-30 (163.52.0.0/16), so it appears to have been issued again from APNIC's pool.

RDAP lookups
Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
