DNS is responsible for mapping what to what?

IP address to subnet mask
Domain name to IP address
Host name to URI
Server name to MAC address

The correct answer is: Domain name to IP address

The role of DNS (Domain Name System) is to translate human-friendly domain names into IP addresses, which are used by computers to identify each other on the network. This function is essential because while users prefer to navigate to websites using easily remembered names (like www.example.com), computers need numerical IP addresses (like 192.0.2.1) to communicate over the internet. A primary function of DNS is to maintain a database that maps these domain names to their corresponding IP addresses. When a user types a domain name into a browser, DNS servers are queried to resolve that name into an IP address, allowing the browser to load the desired website. This mapping ensures that users can simply remember the domain name without needing to know the underlying numeric addresses, facilitating easier navigation and improved user experience on the internet.
