DNS serves to

• A. Provide encryption for web traffic
• B. Manage routing tables in routers
• C. Map domain names to IP addresses
• D. Store user credentials

Answer: (C)

Domain names are easy for people to remember, but computers reach resources by numeric IP addresses. DNS acts as a distributed directory that translates a domain name into the corresponding IP address so a browser can connect to the correct server. When you request a page, your device asks a DNS resolver, which may query root, top-level domain, and authoritative servers to resolve the name, often using caching to speed future requests. Once the IP is found, the connection can be established and the page retrieved. DNS doesn’t encrypt web traffic—that’s handled by HTTPS with TLS. It also doesn’t manage routing tables in routers or store user credentials. The function here is specifically mapping domain names to IP addresses.
