What is the IP address of my home computer from the perspective of the outside world? I need this in order to grant myself permissions to connect to a mysql database on a work server. I'm working on an Ubuntu 14.04 computer. Here is my output from the command ifconfig

selah@selah-Aspire-5745:~$ ifconfig

You can use curl or dig but even wget

     curl -s icanhazip.com    # or
     curl -s ident.me

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

There are many site that offer this kind of services. If you need to know it often you can add in your alias file (usually ~/.bash_alias) or on .bashrc the following alias

     alias getmyip='dig +short myip.opendns.com @resolver1.opendns.com'
     # or alias getmyip='curl -s icanhazip.com'

and after invoke it with your new command getmyip.
It works too 

     wget -q -O - checkip.dyndns.org | sed -e 's/[^[:digit:]\|.]//g'

You can find your public IP address by browsing to the site http://www.whatismyip.com from the computer that you want to find the IP address for

Even easier, you can type "What's my IP address?" into Google
