No transfer record matches. APNIC's statistics show it available on 2022-09-21 and allocated (dated 2022-09-21) on 2022-09-22. The tracker saw this range released from hold on 2020-04-14 (103.60.97.0/24), 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 2020-04-14 and available on 2020-04-15. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2018-10-10, 552 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 2019-10-10. 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 assigned (dated 2015-06-11) on 2018-10-10 and reserved on 2018-10-11. 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 2019-10-10. 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 2015-06-11 and assigned (dated 2015-06-11) on 2015-06-12. It moved from APNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by APNIC.

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.
