	While the difference may appear to be quite subtile, the
comparission is not a good one. Basically, computers on the same
subnet can freely communicate can freely communicate with one
another while computers on seperate subnets cannot communicate with
the assistance of a rounter, and that holds true even if they both
run on the same network.

	We're just now starting to impliment this here and I am far
from an expert in this kind of thing but, for example, I'm burning
in a new server right now which has two NICs it - one NIC handles
internet traffic and the other is on an isolated management subnet
via which we access the server. While both NICs are installed on the
same server and right now they are both connected to the same
switch, but we can't access the Internet from the management subnet
and the management subnet cannot be accessed from the Interenet.

	I am sorry to say this but I am going to have to bail out of
this discussion. The last word I am not after - feel free to reply
and, rest assured, I'll read it. The problem is that the reality
here is that we are simply wasting our time. Truth be told, you are
right and so I am. The problem is that there are no absolutes. There
may not even be an end in sight. Frankly, it doesn't matter what we
do in order to try and secure a server or how advanced the toys we
use to secure it with are someone, some day, is going to figure out
a way to get around whatever it is that we did. It's been said that
the only secure box is a box that is not connected to a network but
even that isn't true - I've got a surplus monitor here that has an
ID tag on it suggesting that it was once used by the NSA. It weighs
about 150 pounds. One need not be a genius to see that the majority
of it's weight is the result of the metal shield which is apparently
there to prevent the escape of electronic waves of some sort...
