Web1 day ago · When subnetting a network, it's important to determine the number of hosts that will be assigned to each subnet. Following are the steps to follow to help calculate the number of hosts per subnet. Determine the subnet mask or prefix length for the network. Convert the subnet mask or prefix length from decimal notation into binary.
WebTo use the host's formula in this scenario, you take the subnet mask 255.255.255.0 and convert it to binary. This would give you: 111111111 11111111 11111111 00000000. As you can see, there are eight 0s in the subnet mask. To use this with the host's formula, you would calculate 28 - 2.
