Getting WAN IP on console or shell script.

There are few other guide in getting your current WAN IP on Linux console or fetching it within a shell script. But this one works for me.

1. To get the current WAN IP:

$> echo "$(wget http://automation.whatismyip.com/n09230945.asp -O - -o /dev/null)"

2. For LAN IP address/es:

$> ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}'
