I've sometimes thought it would be useful when I wanted to hide a route. But security via obscurity just makes it that much harder to fix something. Many more times than this would have been useful, I've been able to identify at which router a problem was by a 'traceroute' that told me into which router by which interface I was going. When the owner of the router might not even have known. Or I have had attempts to do this foiled by routers that used an internal loopback IP address. On the whole, then, I guess I would vote, "no". -- Joe Yao ----------------------------------------------------------------------- This message is not an official statement of OSIS Center policies.
