Getting IP Address on server

Hi,
I'm running a server using cjb.net free redirection and Cjb.netter, a dynamic IP address re-assignment thing, which is good only for HTTP. Currently, I have a page that displays the server's current IP address (to allow FTP, news, etc) but the only way I can do this is using a program that accesses ipconfig.exe. Is there a script/exe way I could do this? Currently, it returns them all, and it being text-only, it doesn't display line breaks, so it's just one big mess. I know there's got to be a better way, I'm just afraid I don't know what it is.

Any help or suggestions would be appreciated.

You might want to check out resourceindex.com, they have lots of scripts there in perl, c, c++, ect.. I am pretty sure they have what you are looking for.
