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 allocated (dated 2011-10-04) on 2012-05-13 and allocated (dated 2012-05-14) on 2012-05-15. (Until 2013-03-05, ARIN's statistics list only what's issued.) The registration was replaced with one for a different holder record, and public sources don't say why (a transfer not yet logged, a return and reissue, or an organization record change).

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.
