How do I find my IP address on a Mac?

What if en0 is the wrong interface?

The Wi-Fi interface name can differ between Macs. Run networksetup -listallhardwareports in Terminal to find the exact interface name (en0, en1, and so on) tied to Wi-Fi.

The same command reveals the Ethernet port name if you are on a wired connection, which you can then use with ipconfig getifaddr.

What if System Settings and Terminal show different results?

Both methods should show the same private IP. A mismatch usually means you are connected to both Wi-Fi and Ethernet at once, and each command is checking a different interface.

If public versus private IP is still unclear, public vs private IP covers the basics first.

How do I find my router own IP (gateway)?

In the TCP/IP tab under Network > Wi-Fi > Details, the Router field is your router private IP. From Terminal, netstat -nr | grep default shows the same information.

For more on reaching the router admin page, see find your router IP.
