... There are five steps to subnetting: 1. Determine the number of subnetworks needed and the maximum number of hosts on any subnetwork. 2. Determine the number of bits to “steal” from the host bit portion of the IP address. Use the formula 2N – 2 = the maximum number of subnets available, where N = the ...
