What is the primary function of the DNS?

The primary function of the Domain Name System (DNS) is to translate human-readable domain names, such as www.example.com, into machine-readable IP addresses, such as 192.0.2.1. This translation process is essential for the functionality of the Internet because while users prefer to navigate websites using easy-to-remember domain names, computers communicate over the Internet using IP addresses.

When a user enters a domain name into their web browser, a DNS resolver queries the DNS servers to find the corresponding IP address. Once the IP address is obtained, the browser can connect to the web server that hosts the website, enabling access to the requested content. This essential service of translating and routing ensures that users can navigate the web seamlessly and efficiently.

In contrast, hosting web servers, providing web design tools, and managing database connections are distinct functions that do not relate to the core purpose of DNS, which is focused specifically on name resolution.
