What is the primary function of the DNS in relation to URLs?

• A. It translates a URL into the corresponding IP address
• B. It stores websites on servers
• C. It assigns IP addresses to devices on a local network
• D. It encrypts web traffic

Answer: (A)

DNS acts like the internet’s phonebook, turning human-friendly domain names in URLs into the numeric addresses that computers use to locate servers. When you type a web address, the DNS system looks up that name and returns the IP address of the server hosting the site. Your browser then connects to that address to fetch the page. This lookup can involve nearby caches and a chain of DNS servers (root, top-level domain, and authoritative servers) to quickly and accurately find the right address. DNS doesn’t store website content, doesn’t assign local device IPs, and doesn’t by itself encrypt traffic—its job is simply translating the name you type into the address the browser uses to reach the site.
