Finding a program's IP address to block

[Megaman0]

Can someone tell me how to find a programs IP address so it cannot "call home". I tried blocking it with a firewall, but it still manages to "call home". For example, when using TuneUP Utilities 2010.

Thanks guys!

Use a firewall like Comodo or whatever you like. When a program tries to call home, firewall should detect the outbound connection and notify you if you want to allow or block it.
