There are a few apps there reveal your local IP, but because I use airport, every computer starts with 10.0.1.X. I need to find out the public IP which is the one your internet provider gives you, and because mine is not static, I need to check it. There is a script which is designed for Acquisition which checks all the Gnutella ports, it tells me the public port but I want something simpler. I know you can check it in System Profiler, but once again, I want something simpler. I would write a script but I don't know how to. Anyone?
