To calculate the number of host bits per subnet, use the formula:
Number of Subnets = 2^N
Where N is the number of host bits.
For example, if you need 8 subnets, you would use N = 3, which gives you 2^3 = 8 subnets. So the number of host bits per subnet is 3.
To calculate the number of host bits per subnet, use the formula 28 – X = Y, where X is the number of subnets and Y is the number of host bits. For example, if you have 16 subnets, 28 – 16 = 12, meaning there are 12 host bits per subnet.
