Broadband External IP Address from Command Line

Sep 16, 2013 · 1 min read · Linux

Just typing "What is my external ip address" into Google is normally the most convenient way to find your external public IP address when you're behind a NAT'd broadband connection. The site ipconfig.me offers an alternative and clean way to get it from the command line, for example for use in a shell script:

1server# curl ifconfig.me
2132.231.56.65
3server# curl ifconfig.me/host
4132-231-56-65.myisp.com

They have a range of options to return IP, Hostname, UserAgent, etc. The one I may be using is ifconfig.me/all.json or all.xml, to make it even easier to read into a Perl or Python script!
