Likely issued from APNIC-controlled inventory
No transfer record matches. APNIC's statistics show it available on 2018-12-14 and allocated (dated 2018-12-13) on 2018-12-15. It moved from APNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by APNIC. Another change to this range was reported the day before or after (2018-12-13: Released 103.127.36.0/22), so the before-and-after statistics may include it.

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.
