In a typical DNS query without any caching, there are four servers that work together to deliver an IP address to the client: recursive resolvers, root nameservers, TLD nameservers, and authoritative nameservers. DNS clients, which are built into most modern desktop and mobile operating systems, enable web browsers to interact with DNS servers. What is a server?Ī server is a device or program dedicated to providing services to other programs, referred to as ‘clients’. This all happens thanks to DNS servers: machines dedicated to answering DNS queries. Browsers then use those addresses to communicate with origin servers or CDN edge servers to access website information. When users type domain names such as ‘’ or ‘’ into web browsers, DNS is responsible for finding the correct IP address for those sites. The Domain Name System ( DNS) is the phonebook of the Internet.
