Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it not issued on 2010-08-01 and allocated (dated 2010-08-02) on 2010-08-03. (Until 2013-03-05, ARIN's statistics list only what's issued.) The tracker saw this range released from hold on 2010-06-07 (209.217.224.0-209.217.255.255), so it appears to have been issued again from ARIN's pool.

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.
