10. Red info systems is setting up a network for 100 computers to accommodate new recruits in its production department. The management wants the network to be efficient and has instructed the network administrator, Keith Turner, to ensure this, while setting up the network. In order to establish an efficient network, Keith has decided to subnet the network. The network address allocated for this network is 194.168.10.0. Keith has decided to divide the network into four subnets. Determine the subnet mask for this network.
