If you are trying to find out what your public external IP address is, you typically go to a web site specifically for this purpose, such as ipchicken.com [1] or whatsmyip.org [2]. Thanks to cURL [3], you can easily do this from the command line too. To install cURL, run the following command:
- Ubuntu: sudo apt-get install curl
- openSUSE: sudo zypper install curl
To find out what public IP you are using, run this command:
curl ifconfig.me
A single line will be returned containing your public external IP address.
