       where the last octet of your ip = 140+station #
    mask 255.255.0.0

        10.196.255.255 is our broadcast
        10.196.0.1   is our gateway must be in our local subnet

        what is the smallest usable ip in our subnet ?
            ans: 10.196.0.1
        why not 10.196.0.0 ?
             ans: because this is the ip addr of our network subnet

        what is the largest usable ip in our subnet ?
