| I gave my home setup as an example. A very simplified example. But,
you

|
| When I sit at my desk at work, and connect to a website (or rather I
| request it), it goes to the local intranet server for that location.
| From that server it is sent to the main intranet server for the
| platform that I am employed in. Then it is sent to the main intranet
for
| the entire corporation, based in New York City, USA, then *that*
server
| makes a simple request for the page. It is then returned back
through
| that path to my PC. All of that is providing that it meets the 4
levels
| of criteria that is required to access a website from a user
terminal.
|
| Now, please tell me how you intend to get the IP Address of my work
PC
| from your website? If, and only if, you can explain that to me will
I
| even consider an IP Address to be of any interest, which it isn't.
Or
| rather, it shouldn't be as it is worthless, unreliable, and useless.

Excuse me, I did mention the word but had the intention of conveying
verification in mind.
In other words comparing an IP to a list/db of authorized users.
As in I sign up as a member and my user ID, PWD and IP are recorded
for future verification.

Yes, that's what I ment about "we wouldn't have
had this exchange and would have known how to identify a proxy from
the article." In no way did I say you are out of wack with your
point.
Just that there are some uses in IP verification.

Well, if it is not a matter of verification against my business db of
authorized user/clients I don't care.
But if it is a matter of you committing a fraud on my business, after
I get your businesses IP I produce a SUBPOENA DUCES TECUM.
