Solution Preview
If we breakup the 32 bit IP address as (net : subnet : host), then
number of hosts in each subnet = (2 ^ number_of_host_bits) - 2 , as host numbers consisting of all 0 and all 1 bits are reserved.
Similar restriction is also applied to subnets by older standards, however recent standards do allow use of all 0 bits and all 1 bits subnets. Hence,
number of subnets = (2 ^ number_of_subnet_bits) , as per recent standards.
number of subnets = (2 ^ number_of_subnet_bits) - 2 , as per older standards.
This answer is following recent standards.
