A Domain Name System (DNS) server is a computer system that stores the addresses of IP addresses for use in Domain Name System (DNS) transactions. DNS servers are used to resolve domain names to IP addresses.

They are also used to generate human-readable names for hosts on the network.

DNS is a hierarchical naming system where each domain name is mapped to a series of IP addresses. The root zone is the first zone in the DNS hierarchy, and it contains the addresses of all the other zones.

DNS clients query the DNS server for the IP addresses of domain names they want to resolve. The DNS server then queries one or more other DNS servers for the domain name’s corresponding DNS records.

A DNS server can be used for a variety of tasks, including providing name resolution for domain names, hosting authoritative DNS servers, and caching DNS records.
