get full client details in client

Question

Hi, 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 http://www.geobytes.com/IpLocator.htm but it just tells city, country and another things but it doesn't show what I need. Thanx

Being realistic, you might as well use a service such as Google Analytics - they'll be able (where possible) to tell you the origin domain which is about as accurate as you're likely to get. (In many instances, you won't be able to obtain even something this useful.)

Alternatively, if you require this in something approaching real-time, you'll could attempt to obtain the reverse name lookup of the IP address, etc. or use one of the many IP to location based services available.

However, I wouldn't labour under the illusion that you'll be able to discover who's browsing your website in a reliable and meaningful way at the level of detail you seem to believe is possible.
