You are developing a school network with the class C address 192.168.2.0/24. There will be three
computer labs with 30 computers each that need to be on different sub-subnets. Forty eight classrooms with
one computer each that will comprise a single sub-subnet. The administrative office and guidance office
contain a total of seven computers which will need to be grouped together. Plan for four more mini labs with
six computers to each sub-subnetwork. Divide the network using variable length subnet masks. Complete
the information required below. Remember to work from largest to smallest.
