No transfer record matches. ARIN's statistics show it available on 2015-04-23 and allocated (dated 2015-04-24) on 2015-04-25. The tracker saw this range released from hold on 2011-08-03 (45.2.0.0-45.255.255.255), 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.
