DNS servers manage which server a user will access when they enter a domain name into their web browser by converting requests for names into IP addresses.
Recursive resolvers, root nameservers, TLD nameservers, and authoritative nameservers are the four categories into which all DNS servers fall. Domain name system, or DNS, converts a domain name into an Internet Protocol (IP) address. In light of this, the DNS converts IP addresses into a hierarchy of domain names. Internet Protocol (IP) addresses are translated into domain names during a reverse DNS lookup. Without DNS servers, the internet would not function at all. It is their job to convert domain names into IP addresses. Computers then identify and connect to those web servers using those IP addresses, directing users to the appropriate websites.
