Methods to detect public IP address in bash

As part of an installation script, I want to make an "educated guess" about the machines public IP address. It should be as robust as possible, working on a variety of hosts and platforms. Here is an example:

https://gist.github.com/4669037

This script uses 3 methods and then defaults to the value of

/etc/hostname
. I have only tested this on Ubuntu so far. Will this be likely to work on other distributions? And are there additional methods that I could add?

Answer
curl ipinfo.io/ip

Or

wget -qO- ipinfo.io/ip

Or

lynx -source ipinfo.io/ip

get public ip address
