Whenever you make a request, the server has to know the IP to send the response to. In addition, most browsers send information about what they are and the OS they are running on. A short server-side script can then extract all the information with ease and post it back to you.

Your IP address will be in the IP packet. The user agent field of an HTTP header will state exactly what OS you are running and which browser. Your ISP can be obtained using the IP address.

Very simple. The web cannot work without this information. All it shows is someone is aware how to dissect an HTTP request via a TCP/IP packet.
