What is the function of DNS in a network?

• A. Resolves domain names to IP addresses.
• B. Dynamic adds IP addresses automatically.
• C. Routes traffic between networks.
• D. Stores email messages.

Answer: (A)

DNS provides naming resolution: it translates human-friendly domain names into the numeric IP addresses that computers use to locate and connect to services on a network. When you enter a web address, a DNS resolver asks DNS servers for the corresponding IP, and once that address is known, the connection proceeds. This makes it possible to use memorable names instead of having to remember exact numbers. Dynamic IP assignment is handled by DHCP, not DNS, so DNS isn’t responsible for adding IPs automatically. Routing between networks is the job of routers and routing protocols, not DNS. Storing email messages happens on mail servers, not DNS.
