need info re: new set up vista to ventrilo

[konabean]

hi I have never set up Ventrillo onto my cpu. can anyone tell me what the ip address designation in setup does to the system operation? The Vent notes gives an IP address to use but also says it may change and thus needs to be changed on my CPU ever so often. If so how does one do this? As you can tell I am a novice on computer stuff.

Also, I don't have a mic and only speakers is this a problem ???
what mic set up do you recommend ? thxs!!
