No. Because it's utter nonsense. There is no "stealth" in TCP/IP.
Period. If a given host is not reachable from your current location,
then some router along the way will respond with a "destination
unreachable" ICMP packet. Not receiving a response normally means that
for some reason your packets (or the responses) are being dropped, which
indicates that the target is there rather than the opposite.

That would be the correct way to put it. However, Gibson insists in
deceiving people into believing they could magically hide their
computers by not responding to packets. Which, of course, they can't.
