This is lifted from the BT forum as I'm not at home but matches my experience.
Primary DNS: 188.8.131.52 (OpenDNS) or 184.108.40.206 (Google DNS)
Tracing route to google.com [220.127.116.11] <- Incorrect BT IP address
BT default DNS:
Tracing route to google.com [18.104.22.168] <- Correct Google IP address
