No transfer record matches. ARIN's statistics show it not issued on 2010-06-30 and allocated (dated 2010-07-01) on 2010-07-02. (Until 2013-03-05, ARIN's statistics list only what's issued.) The tracker saw this range released from hold on 2010-04-12 (174.128.0.0-174.128.255.255), so it appears to have been issued again from ARIN's pool.

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.
