What is the primary function of DNS?

• A. DNS translates domain names to IP addresses.
• B. DNS routes packets across networks.
• C. DNS stores email messages on a server.
• D. DNS assigns IP addresses to devices automatically.

Answer: (A)

The primary function of DNS is to translate human-friendly domain names into machine-readable IP addresses so devices can locate and connect to the correct servers on a network. When you type a web address, DNS looks up the corresponding numerical IP and your browser uses that address to reach the site. Think of DNS as a phonebook that converts names like example.com into the actual address the network uses to route traffic. It doesn’t handle packet routing (that’s done by routers), it doesn’t store email messages (that’s the job of mail servers), and it doesn’t assign IP addresses automatically (that’s DHCP).
