Likely issued from APNIC-controlled inventory

No transfer record matches. APNIC's statistics show it available on 2025-09-22 and allocated (dated 2025-09-21) on 2025-09-23. The tracker saw this range released from hold on 2020-10-21 (155.35.1.0/24), so it appears to have been issued again from APNIC's pool.

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

APNIC's statistics show it reserved on 2020-10-21 and available on 2020-10-22. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2019-10-10, 377 days earlier. That is APNIC's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2020-10-10. 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 1992-02-04) on 2019-10-10 and reserved on 2019-10-11. 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 2020-10-10. That is what APNIC has done, not a rule it states. This does not confirm availability.

Inventory
No effect on APNIC applicant inventory

No transfer record matches. APNIC's statistics show it reserved on 2016-03-02 and allocated (dated 1992-02-04) on 2016-03-03. The tracker saw it removed from registration on 2015-09-02 (182 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.

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.
