In other words, Tor does not always use the same 4 Tor relays.Ī route that Tor chooses is called a Tor circuit that is used for a limited time for a limited purpose. When visiting different websites, for better anonymity, Tor uses different routes through the Tor network. The advantage of this is, that this improves the anonymity for everybody. Therefore thousands of users are sharing the same IP addresses every day. Tor exit relays are used by thousands of other users at the same time. Thanks to Tor's need to know architecture, the Tor exit relay does not know the user's IP address, let alone identity. Otherwise the user could not visit the website. When vising websites using Tor, the Tor exit relay necessarily needs to know the server which the user is connecting to.
When using Tor, websites visited by the user, can only see the IP address of the Tor exit relay. Tor does that by replacing the user's real IP address with an IP of a Tor exit relay server. On the internet, the user's IP address acts as a globally unique identifier that is commonly used to track all of the user's activity. The role of each server is to move that data to another server, with the final hop moving data to the end site.
It works by directing the user's internet connection through multiple Tor servers, called Tor relays. Thousands of volunteers are running computer servers that keep users anonymous on the Internet. Tor a software providing anonymity on the internet.
