: The same user from different IP-addresses? Has anybody encountered the situation when the same user from the same session ID and the same browser requested 2 different scripts on the same webserver

There may also be a case of session hijacking in which case the users session is hijacked by a cracker and used to access the legitimate user's account. In this case we may find the user to be "virtually" accessing the web content from two different IPs.

Yes, it's normal. ISPs, particularly AOL and mobile providers, can route traffic through different proxies which will change the IP address of a user as they surf the web. Users using a proxy server can also experience this. This is why depending on a static IP address from a user during a session is not recommended for any kind of identification system on a website.
