# How Do You Determine The Number Of Hosts In A Network?

The element in determining the host numbers of subnet masks is that the sum of the 0 values ​​available is found by the formula [2 n -2]. the sum of the 0 values ​​at hand is 24 bits. The formula [2 n -2] always gives us the total number of hosts .

## How do you calculate the number of hosts per subnet?

Furthermore, how do you calculate the number of hosts? The total number of IPv4 host addresses for a network is 2 to the power of the number of host bits, which is 32 minus the number of network bits. For our example of a /21 (network mask 255.255. 248.0 ) network, there are 11 host bits ( 32 address bits – 21 network bits = 11 host bits ).

## How to find the network and host address?

Everything is binary, so we take the number of zeros in the subnet mask (32-X), raise 2 to that power, and then subtract the network identifier and broadcast address from the result. If you just want to know how many IP addresses (not quite the same thing as hosts) are in the range, don't bother subtracting 2.

## How does the number of hosts in a network depend on?

The number of different networks possible in each class is a function of the number of bits assigned to the network ID, and likewise, the number of hosts possible in each network depends on the number of bits provided for the host ID.

## How to find the number of hosts in IP _ range / X?

If you are just wanting to know the number of hosts in any IP_Range/X: Everything is binary, so we take the number of zeros in the subnet mask (32-X), raise 2 to that power, and then subtract the network identifier and broadcast address from the result.
