DNS resolution converts a domain name to what?

DNS resolution converts a domain name to what?

• A. A port number
• B. An IP address
• C. A MAC address
• D. A domain name

Answer: (B)

DNS resolution maps a human-friendly domain name to an IP address that identifies a specific host on a network. This numeric address is what the networking stack uses to route and deliver data to the correct machine. A port number, which indicates a particular service on that host, is separate information and is not produced by DNS. MAC addresses are tied to physical network interfaces and are discovered on the local network, not through DNS. The result of DNS lookup is the IP address (IPv4 or IPv6) corresponding to the domain name.
