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.Дespite the number of steps involved, the process of resolving a DNS query and displaying a websiteвЂ™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 deviceвЂ™s network settings, and the DNS resolver responds with the IP addresses on the internet where that website is located.
