Whether the actual user's IP changes isn't relevant.  The question is, can
the IP of a proxy server between the user and you change.  And that's quite
possible.  Consider the situation where the round-robin DNS of a bank of
proxy servers expires during the user's browsing session, or a bank of
proxy servers behind a load balancer on the user's side.  Since all the
HTTP server ends up seeing is the proxy server's IP, you could potentially
have the same user dancing around all over the place, IP address-wise.
