Lots of times you need to determine your public IP address, if you are using Linux operating system to power your PC, you may use some good console commands to guess your public IP address.

Most of these methods will return you the local IP and not the public IP of your proxy if you are behind one.

wget

wget -q -O - checkip.dyndns.org|sed -e 's/.*Current IP Address: //' -e 's/<.*$//'

That will return your local IP

curl

curl -s checkip.dyndns.org|sed -e 's/.*Current IP Address: //' -e 's/<.*$//'

That one is going to give your current IP, being it public or private. Something like running ifconfig or ip adds

curl ifconfig.me

That is going to return you the public IP you are using to access internet. If you are behind a NAT or proxy, it will the IP of that proxy.

Lynx

lynx -dump ifconfig.me | grep 'IP Address'

That is also going to return your public IP.

As you can see, there are a lot of ways to check your Public IP address using console commands in Linux. Of course you can always open a browser and enter any of those URIs and check there.
