Inventory effect unknown
No transfer record matches. APNIC's statistics show it not listed on 2009-08-18 and allocated (dated 2009-08-18) on 2009-08-19. 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.

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.
