Inventory
Likely issued from APNIC-controlled inventory
No transfer record matches. APNIC's statistics show it available on 2014-07-11 and allocated (dated 2014-07-11) on 2014-07-12. The tracker saw this range removed from registration on 2011-11-14 (163.53.0.0/16), so it appears to have been issued again from APNIC's pool.

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.
