How does the DNS server work?

  • The user types the address of a website in the browser, e.g. https://example.com
  • The browser sends a DNS query to the DNS server asking it to return the IP addresses for the selected example.com (domain’s tld nameserver)
  • The DNS server in response returns the IP addresses of the server to which the indicated domain is assigned.
  • The browser connects to the server with the specified IP address requesting to display the page for the domain https://example.com

DNS lookup process can is divided into separate DNS queries a recursive DNS server acts on behalf of the end host (a laptop, server, etc.) to find the IP address of a domain name that is not authoritative and return this information to the requesting end host. An authoritative DNS server user types an address into a web browser, or an application calls out to a given name of a resource on the Internet.
