You are probably used to all these “get my IP” or “find my IP” kind of site, which show your external / Internet IP on a Web page.
However you might be facing some challenge if you are on a CLI only kind of machine. Fortunately there is a few ways to find your public IP from the console, here are two easy ones :
1. Use cURL toward our simple IP page :
curl itechlounge.net/ip
2. Use the “DIG” DNS utility if it is present on your system, by querying OpenDNS servers :
dig +short myip.opendns.com @resolver1.opendns.com
NOTE : DIG is usually a part of “dns-utils” package on modern Linux systems.
