The sticker on the back. If there isn't one, make up one. It's simply 6 two digit hex values that is not the address of any other device on your network.

I have tried that..... I have am using the example Ethernet/chat server from arduino but can not get my router to see the arduino lights on shield are on or flashing I have put a free ip address in and gateway ,subnet address ….. I don’t have to download a new library file do I ?????

I think that this topic needs to be moved to Networking. The problem is most likely one of router configuration. The Arduino needs a static IP address (from the pool managed by the router). Most likely, the router does not see that the Arduino has whatever free address you assigned it because the router didn't assign the address. Since the router didn't assign the address, the router thinks that the address is unused.
