Once your web browser knows the IP address of a website, it communicates with the server at the IP address, and displays the received web content that is available on the URL.ĭespite the number of steps involved, the process of resolving a DNS query and displaying a website’s content happens very quickly. This information is then returned to your browser running on your computer. Finally, the resolver communicates with these Authoritative Name Servers, querying the fully-qualified domain name, and receives 1 or more IP addresses which are the servers that host the content required.The DNS resolver then communicates with a server from this list, passing the domain name and TLD to the server, and gets a response of 1 or more IP addresses for the Authoritative Name Servers for the domain name and TLD.The response to this is 1 or more IP addresses for TLD servers. First, the resolver communicates with a DNS Root Server, to find out which servers hold information for the Top-Level Domain (TLD) part of your DNS query, e.g.com or.

When the DNS resolver receives such a query, it communicates with several types of servers in a chain to find out which DNS server holds the information to answer the query. When you visit a URL (a website address) in your browser, your device sends a DNS query to the DNS resolvers it knows about via your device’s network settings, and the DNS resolver responds with the IP addresses on the internet where that website is located.
