Which Linux command resolves a domain name into an IP address?

• A. host -t a hackeddomain.com resolves a domain name into an IP address.
• B. ping hackeddomain.com
• C. ifconfig hackeddomain.com
• D. dig hackeddomain.com +short

Answer: (A)

DNS resolution translates a domain name into its IP address. The host command is designed for quick DNS lookups, and when you use it with the -t a option, you’re asking for the A record, which is the IPv4 address associated with that domain. The output directly reveals the numeric IP, making it the cleanest way to turn a domain into an address. Other commands can reveal an IP in different contexts—ping performs connectivity tests and will show the IP as part of its output, and dig +short can also return the address—but host -t a is the straightforward, targeted tool for resolving a domain to its IPv4 address.
