No transfer record matches. ARIN's statistics show it allocated (dated 2000-05-24) on 2013-07-28 and allocated (dated 2013-07-29) on 2013-07-30. The holder's record is the same before and after, so this is a change to the registration, not a change of holder.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.
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.
