Domain Name System

DNS is the phonebook of the Internet. It translates human readable domain names like to computer addresses such as 11.423.35.1. DNS is the first step of looking up a webpage.

Most of us use the DNS servers provided by our ISP. DNS in not encrypted and your ISP can easily see all your internet DNS requests. Once again, your browser's private or incognito mode does not anonymize your internet requests.
