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

APNIC's statistics show it reserved on 2016-06-22 and available on 2016-06-23. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2015-04-23, 426 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 2016-04-23. 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 2011-02-01) on 2015-04-23 and reserved on 2015-04-24. 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 2016-04-23. 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 2011-02-01 and allocated (dated 2011-02-01) on 2011-02-02. It moved from APNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by APNIC.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.

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.
