If your app is facing the internet, its best to assume that the ip address that you recieve is that of some AOL proxy server. It this address is really only good for reporting on where your requests are probably coming from. In our environment, we have a reverse proxy in front of our web servers. Our apps always see the address of our own proxy server.

However, a proxy is allowed to (and often does) change the packet. Be aware of that in your programming (which means, among other things, no session tracking via IP address).

As even this e-mail bounces through umpteen routers, and none of these will modify the remote address. So, as far I can tell this won't happen - what you have to worry about is Web Proxies as these do send the request to the web server themselves, and your web server will see them as the remote host and not you.
