They hide the servers for a reason, and one of the reasons is that users (script kiddies) using the info about the server to look what server to kill (DDOS), then they kill the server with most users on, and then they only have to kill 1 or 2 persons in the channel, and now we see a regular take over

.. so if they making effort to hide the server address, then i dont think you will find any fast and simple way to get that info, the only way i guess is to ask the user..
