How can I find out my public IP address via command line?

Nifty command for a quick lookup

Nov 6, 2024

Here’s a quick way to find out your public IP address via a DNS query:

nslookup / windows:

nslookup myip.opendns.com. resolver1.opendns.com

dig / Linux:

dig +short myip.opendns.com @resolver1.opendns.com

It leverages a dns server at OpenDNS to return the source IP of the request itself. Nifty for times when you don’t have a browser handy. 😄
