I am confused.
I have a question that says assign the 3rd usuable subnet to the serial interface of the router but note the sub zero subnet is not usable. The network is 192.168.1.0 / 240. this is just an example. Assign the last usable IP from the 3rd usuable subnet.
I know the first networrk is 0
2nd is 16
3rd is 32
What is my answer and shall i still consider the network 0 even though the question tells me to consider subnet zero is not usuable.
