how can I use my domain name to direct people to my shoutcast

[raingod42]

if you have a server running on your machine (www.mydoamin.com points to a machine you administer), you can set up the winamp.mydomain.com. while you're doing that you set the ip - so no need to point them to an IP. you also need a a playlist file - so the address would be winamp.mydomain.com/playlist.pls
good luck!
