Incorrect. For instance, my wife's ex-company routed all internet from
all of their sites (in several states around the U.S.) are all routed
through the same proxy. This is quite common in larger companies; it
simplifies maintenance.

In this case Richard is correct. Externally, all users behind the same
proxy or router will have the same IP address to the external world. No
one outside the LAN would have any idea what the real IP address is.

Actually, quite possible. It does happen.

Nope. Only those who do not understand how ip addresses work.
And even if it were a billion to 1 - with 4 billion ip addresses out
there, chances are very high it WILL happen.

Perhaps you should learn how ip assignment works before correcting
someone who obviously knows more about it than you do.
