Mostly academic, as I don't know how it would be useful, but if for some reason you need your own IP for programs ALL ONLY on your computer, you can just use 'localhost' or '127.0.0.1'. That's how your computer refers to itself. (EG, if you're running an FTP server on your computer, and want to FTP a file to it from the very same physical machine.)
