How to find your public ip from bash

There are many sites that can show you your current public IP. But only a few of them are designed in a way so you can interact with them from command line using curl for example.

Below is a nice and elegant way to find out your public IP using curl

 
alias myip='curl --silent checkip.dyndns.org | egrep --only-matching "[0-9\.]+"'

root@server:~# myip
1.79.21.123
