Technically yes, but I'd imagine it wouldn't change the external IP. If you can change your IP at will, chances are you're behind a router using NAT (network address translation). If that's the case, no matter what your internal IP is, it will always register on CD and other sites as your external IP (if you're on broadband... dial-up typically results in a different IP every time you connect... come to think of it, even cable and DSL change randomly, but are generally not under the user's control)
As a random note, to find out your external IP, or the IP that sites like CD will see, go to
