What is the primary purpose of a DNS server?

The primary purpose of a DNS (Domain Name System) server is to translate human-readable domain names, such as www.example.com, into IP addresses, which are the numerical addresses used by devices to identify each other on a network. This translation process is crucial because while people find it easier to remember names, computers and network devices communicate using numerical IP addresses.

When a user types a domain name into a web browser, the DNS server is queried to find the corresponding IP address so that the browser can establish a connection to the correct server. This function enables seamless internet navigation, ensuring that users can access websites and online resources without needing to memorize complex numeric addresses.

For context, the other options touch on different aspects of network operations but don't define the role of a DNS server. Assigning IP addresses is typically the function of a DHCP server. Secure remote access relates to different network security protocols and technologies, and managing user accounts falls under directory services or identity management systems, not DNS servers. Thus, the role of the DNS server is distinctly focused on the name resolution process, making it a vital component of internet and network functionality.
