Explanation
Nslookup (Name Server Lookup) is the correct tool because it specifically queries DNS servers to resolve hostnames to IP addresses and vice versa - confirming the identity of an Internet host by name or address.
- Ping (A) tests reachability and measures round-trip latency; it can use a hostname but its purpose is connectivity testing, not name resolution confirmation.
- Traceroute (B) maps the network path (hops) between your machine and a destination; it's about routing, not name/address lookup.
- Finger (D) retrieves user account information from a remote system - a largely obsolete protocol unrelated to DNS or IP resolution.
Memory tip: Think of NSlookup as Name-to-Server lookup - when you need to confirm what name or IP a DNS server knows about a host, NSLookup is your go-to tool.
