I'm a little confused on what a subnet is. My router network ip is xxx.xxx.1.0
and it's subnet is 255.255.255.0. the gateway is xxx.xxx.1.1 Let's suppose that
I've restricted all my computers in the router to be on xxx.xxx.1.200 to
xxx.xxx.1.255. Let further suppose that I have 4 computers on the network.
What would be the subnet addresses I would put into ZAP's firewall zones?

Thanks again for all your help!
