Whose IP adress Tony the address of your internet provider or the address of the attached computer? The ones in ipconfig are the router address and the computer address, the address in 'what is my ip.com' is the address that your ip assigns to you when you log on and would not be put in the router. I suspect the one wanted is the address of the IP provider, I am assuming you are talking about setting up the router it's self not the pc.
