get full client details in client
<p>I want to get full details of a client who visits my site. I know I can get his/her ip by $_SERVER but I want to know where exactly his/her ip is reserved by. For example, I want to know which university visited my website. I used <a href="http://www.geobytes.com/IpLocator.htm" rel="nofollow">http://www.geobytes.com/IpLocator.htm</a> but it just tells city, country and another things but it doesn't show what I need.
Thanx</p>
