There are times when you might require to view the IP address your server is using for outgoing connections. If you are in command line/console/mosh/ssh/rsh, you want an one command solution instead of visiting a page like whatismyip.com using lynx browser or so on. Here is a quick tip that I regularly use to perform this:
Using cURL:
curl ifconfig.co
Using wget:
wget -qO- ifconfig.co
ifconfig.co does it simple and easy.
