Likely issued from APNIC-controlled inventory
No transfer record matches. APNIC's statistics show it available on 2015-12-10 and allocated (dated 2015-12-10) on 2015-12-11. The tracker saw this range released from hold on 2015-12-09 (103.11.0.0/22), so it appears to have been issued again from APNIC's pool. Another change to this range was reported the day before or after (2015-12-09: Released 103.11.0.0/22), 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 2015-12-09 and available on 2015-12-10. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2013-11-04, 765 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 (2015-12-10: Added 103.11.0.0/22), so the before-and-after statistics may include it.

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 2011-10-10) on 2013-11-04 and reserved on 2013-11-05. 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 2011-10-10 and allocated (dated 2011-10-10) on 2011-10-11. 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.
