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

APNIC's statistics show it reserved on 2019-05-14 and available on 2019-05-15. APNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2018-05-01, 378 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 (2019-05-15: Added 203.109.48.0/22; 2019-05-15: Added 203.109.52.0/22; 2019-05-15: Added 203.109.56.0/22), so the before-and-after statistics may include it.

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.
