APNIC's statistics now list it as 'available'; reissue not confirmed

APNIC's statistics show it reserved on 2022-06-15 and available on 2022-06-16. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2021-06-09, 371 days earlier. That is APNIC's own label: whether and when it is reissued is not confirmed.

Hold estimate
Estimated hold end 2022-06-09. 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 2018-12-13) on 2021-06-09 and reserved on 2021-06-10. 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 2022-06-09. 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 available on 2018-12-13 and allocated (dated 2018-12-13) on 2018-12-14. The tracker saw this range released from hold on 2018-12-12 (203.88.100.0/22), so it appears to have been issued again from APNIC's pool. Another change to this range was reported the day before or after (2018-12-12: Released 203.88.100.0/22), so the before-and-after statistics may include it.

APNIC's statistics show it reserved on 2018-12-12 and available on 2018-12-13. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2017-12-06, 371 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 (2018-12-13: Added 203.88.100.0/22), so the before-and-after statistics may include it.

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.
