What is the role of DNS (Domain Name System) in internet protocols?

The role of DNS (Domain Name System) in internet protocols is to translate domain names (such as www.example.com) into IP addresses (such as 192.0.2.1) that computers can understand. It acts as a directory service, allowing users to access websites and other internet resources by using easy-to-remember domain names instead of complex IP addresses. DNS also helps in the efficient routing of internet traffic by providing information about the location of servers and services associated with a particular domain.
