By the looks of it there is only the 1 server, however the server name suggests it is in a pool of servers. The only server given from the /links command is irc.digitalrats.net
this address resolves to 216.40.33.31 which I cant connect on. So I assume /server 216.221.66.144 7001 is the only way on. As a thought make sure you have ident enabled. OR check to make sure something isnt changing the port back to 6667.

Good luck
