a subnet mask is a set of numbers that determines which part of the ip address corresponds to the network and which corresponds to the host.

bacisally it's a numerical filter that seperates an ip address into two different sets of information to allow a network to opperate.

The problem with using ipconfig /all to find your IP when you are behind a router is that you will get your local IP address (ex 192.168.0.100) instead of your external address. In that case you'd be able to get your IP from a website like that or get your IP from the status page inside the router's settings.
