I've pinged IP addrs that I later found out were MIL addrs. Nothing happened. Duh! There are a LOT of IP addrs that aren't in the DNS. How is one to know? I don't know about you, but I flunked telepathy in High School and did worse in clarvoyance. In fact, psionics wasn't wasn't something I was generally good at. That's why I went into engineering. Could it be, that is why ping and traceroute were invented? The argument against port-scanning applies equally well to just about every diagnostic tool we use. Be careful what you wish for, we might all get stuck with it. Then, where would we be?

Better lock me up; I can't count the number of times I've nmap-ed somebody just to find out what OS they were using, either for personal curiosity, or as part of an argument.
Cool. Since you're obviously in the right, how about scanning some U.S. military networks and letting us all know what OS they are using?
If you like, I'll start an argument with you so you have the justification you need to portscan.
