If you're multihomed and your route changes, your address changes. (Yes, this happens). I am profoundly weirded out by reading an IAB member argue that something that's got broad market acceptance is tautologically okay. I agree that there's a real problem here that NAT is trying to solve, but I certainly wouldn't treat it as a given that NAT is the best, or even a good, solution. Melinda
