Likely issued from APNIC-controlled inventory

No transfer record matches. APNIC's statistics show it available on 2016-06-09 and allocated (dated 2016-06-09) on 2016-06-10. The tracker saw this range released from hold on 2015-10-28 (203.201.181.0/24), 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 2015-10-28 and available on 2015-10-29. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2011-06-09, 1602 days earlier. That is APNIC's own label: whether and when it is reissued is not confirmed.

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 assigned (dated 2009-01-27) on 2011-06-09 and reserved on 2011-06-10. 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 not listed on 2009-01-27 and assigned (dated 2009-01-27) on 2009-01-28. It wasn't in APNIC's statistics before, so it wasn't APNIC's unissued inventory; it may have come from another registry in a transfer not yet in the log.

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.
