No transfer record matches. ARIN's statistics show it not issued on 2011-06-06 and allocated (dated 2011-06-06) on 2011-06-08. (Until 2013-03-05, ARIN's statistics list only what's issued.) The tracker saw this range released from hold on 2011-05-18 (71.19.128.0-71.19.255.255), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2011-06-06: Remove 69.57.208.0-216.250.127.255; 2011-06-06: Add 71.19.144.0-71.19.159.255), so the before-and-after statistics may include it.

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.
