How do I see the public IP of a rig?

[sebas1382000]

I have a dynamic ip router.
And I have connected the rig through an ethernet.

But my computer is connected to the internet through usb by the modem ...

There is some program to be able to see the public ip of my rig?. it is because they ask for it in the pool

Thanks for the help
