Sorry I'm coming into this discussion so late. I tend not to read work
email on weekends for my own sanity.

Then there are schools that put a hundreds of classroom machines on one IP.

Not true - the combination of IP address and PORT must be unique, not just
the IP address. This is the essence of how NAT and proxies work.

Yes, once again, I agree with this.

I don't know what you mean by I've seen on some webpages [sic] that
My [sic] IP is displayed as both exernal and internal. The IP
address is for the internet and there is only one. You may have
internal routing. That is different. I don't know what you mean

Mark,
Why do want to know the internal NAT ip address of a request? How is
this helpful?
Also, what if the requests come from clients with accounts on the same
multiuser system? Are you trying to figure out how to tell them apart?
There is no NAT address in this case.
Maybe what you are trying
Richard Mixon is, as usual, dead-on right. A good primer is

A major purpose of a NAT style firewall is to hide the private ip
addresses behind the firewall. If it allowed this information out it
would be a security compromise - the network topology behind
I'm trying to figure out is is the client on remote network has a

Here an example:

it's a different person?

If it is the same IP address, it probably is the same person. The
alternatives are highly unlikely, if possible.

If what you are trying to see is the private IP of a machine then you will
only have success if the machine was named the IP. Not likely. The IP is not
stored in the HTTP header (Unless I missed it) but is derived from the
TCP/IP packet. When a machine is on a private network this address is
16 matches
