Tor Project: Anonymity Online. Anonymous web browsing. Achieving Anonymity[edit] When browsing the web, the computer connects to the target server by contacting the web page with the user's IP address and sharing other computer information, including the browser and operating system version.
This information can be used to track the user. However, a certain degree of anonymity can be achieved by using a proxy server or a VPN server. The proxy server works by redirecting the communication through itself. The browser's IP address is then only shared with the proxy server while the target website only sees the proxy server's information.[1]
