Assuming what you want is your external network address, not the 192.168.1.x address your computer pulls from the router, here are two quick and simple ways:
1) In your browser go to: http://whatismyipaddress.com/
2) Log into your router and you should be able to easily find it there. For me, with an Actiontec router, it is on the first page displayed.
