The Domain Name System (DNS) serves as a critical component of internet infrastructure that translates human-readable domain names into machine-readable IP addresses. This mapping process allows users to access websites using easy-to-remember names rather than needing to recall complex numerical IP addresses.

When a user enters a domain name like "example.com" into their web browser, the DNS acts as an intermediary by querying a DNS server, which responds with the corresponding IP address linked to that domain. This seamless translation is essential for web browsing and countless other internet services, enabling efficient and user-friendly navigation of the web.

While firewalls, routers, and gateways play essential roles in managing and directing network traffic, they do not perform the specific function of mapping domain names to IP addresses, making DNS the appropriate choice for this specific service. This distinction highlights the unique role of DNS in the overall networking ecosystem.
