Every change the tracker has found, newest first. It covers ARIN from 2008-12-01, the RIPE NCC from 2010-04-23, APNIC from 2008-02-15, LACNIC from 2012-06-29 and AFRINIC from 2012-10-03.
No transfer record matches. ARIN's statistics show it not listed on 2016-03-01 and allocated (dated 2016-03-02) on 2016-03-03. It wasn't in ARIN's statistics before, so it wasn't ARIN'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.
