No effect on APNIC applicant inventory
No transfer record matches. APNIC's statistics show it reserved on 2026-10-26 and allocated (dated 2023-07-13) on 2026-10-27. The tracker saw it removed from registration on 2026-10-22 (4 days earlier), and it is back with the same holder record it had before, so it went back to its previous holder rather than to a new one: most likely a suspension lifted, a reinstatement or a correction.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2027-10-22. 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 2023-07-13) on 2026-10-22 and reserved on 2026-10-23. 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 2027-10-22. 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 2023-07-13 and allocated (dated 2023-07-13) on 2023-07-14. The tracker saw this range released from hold on 2023-07-12 (103.36.90.0/23), so it appears to have been issued again from APNIC's pool. Another change to this range was reported the day before or after (2023-07-12: Released 103.36.90.0/23), so the before-and-after statistics may include it.

APNIC's statistics now list it as 'available'; reissue not confirmed
APNIC's statistics show it reserved on 2023-07-12 and available on 2023-07-13. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2022-07-07, 370 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 (2023-07-13: Added 103.36.90.0/23), so the before-and-after statistics may include it.
