Easy way to find your public IP in scripts or CLI

There is a lot of online tools that gives your public IP but most of them are either not accepting cli User-Agent or they requires nasty parsing with AWK,grep,sed,etc

Best way to get your public IP address is to use ifconfig.me which only returns the IP simple and efficient.

 $ curl http://ifconfig.me  

The only problem is the responsiveness (few seconds).

Another cool way is to query the opendns servers :

 $ dig +short myip.opendns.com @resolver1.opendns.com

This method is pretty fast but requires the dig command (part of the bind-utils package).
