No transfer record matches. APNIC's statistics show it available on 2016-09-21 and allocated (dated 2016-09-21) on 2016-09-22. The tracker saw this range removed from registration on 2014-05-20 (AS133483), so it appears to have been issued again from APNIC's pool.

Possible future reissue candidate after hold
Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 2014-05-12) on 2014-05-20 and available on 2014-05-21. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, and its statistics show a steady one (a year) only for removals from 2014-07-01 on; this one came earlier, so the tracker gives no estimate. This does not confirm availability.

No transfer record matches. APNIC's statistics show it available on 2014-05-13 and allocated (dated 2014-05-12) on 2014-05-14. 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.
