I know a reason: Millions of AOL users are forced to use a cluster of proxy
servers, so they will not only share a small range of IPs, but the IP might
change from request to request!
I therefore advice you to use sessions instead of IP tracking. This is much
more accurate and should be supported by most webapp-frameworks.
