That's a btinternet dial up account.

host-aaa-bbb-ccc-ddd () btinternet com where aaa.bbb.ccc.ddd is the dynamically
assigned IP address.

Deep Throat trojan uses UDP ports 2140 and 60000 (not sure what's the
server and the client). Probably someone inside your network is using it
or someone in a btinternet.com dialup account is trying to access an
infected host inside your network.
