This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    
Can you clarify your question more? Are you looking to identify users and distinguish between them based on their IPs and other session paramenters? –  AdnanG Sep 18 '13 at 5:51

If X-Forwarded-For header is enable you can use it.

The X-Forwarded-For (XFF) HTTP header field is a de facto standard for identifying the originating IP address of a client connecting to a web server through an HTTP proxy or load balancer. This is an HTTP request header which was introduced by the Squid caching proxy server's developers. An effort has been started at IETF for standardizing the Forwarded HTTP header.


Also you can use to Evercookie for monitoring your users IP/activities.

Evercookie is a JavaScript-based application created by Samy Kamkar which produces zombie cookies in a web browser that are intentionally difficult to delete.
