dig

dig [@server] name [type]

Queries DNS servers and displays detailed results — the modern, scriptable replacement for nslookup on Linux/macOS.

// FLAGS

+shortprint just the answer, no verbose headers

@serverquery a specific DNS server instead of the system default

-xreverse lookup, IP to hostname

// EXAMPLE

dig +short example.com — prints just the resolved IP address(es) for example.com.

// GOTCHA

Plain dig example.com prints a lot of header/footer detail that can look alarming to someone expecting a single answer — +short is usually what people actually want for a quick check.

// RELATED COMMANDS

nslookup curl ip
