When you type a domain name into a web browser, DNS does what?

• A. It translates addresses into hostnames
• B. It locates and translates the domain name into an IP address.
• C. It encrypts the connection
• D. It prints the web page content

Answer: (B)

Typing a domain name prompts DNS to locate the numeric IP address associated with that domain. DNS translates that domain into an IP address (IPv4 with A records or IPv6 with AAAA records) so the browser can connect to the correct server and send the request. This lookup goes through a resolver, which may use cached results or query root, TLD, and authoritative name servers to find the exact address. Once the IP is known, the browser can establish the connection and request the web page. DNS does not encrypt the connection or print the page content; encryption happens later with TLS/SSL, and the page is rendered by the browser after retrieval.
