How do you calculate hosts per subnet?
To calculate the number of possible hosts per subnet, use the formula 2h – 2, where h equals the number of host bits. The reason two addresses must be subtracted is because of the network address and the broadcast address.
How do you determine the number of hosts in a subnet?
You can figure out how many hosts you can have in your subnet by subtracting the number of network bits from the number of total bits: in other words, 32 total bits, minus the number of network bits. Let’s use 26 as an example. A subnet with 26 network bits has six bits available for the host IP addresses.
What is a 255.255 255.0 subnet?
A subnet mask of 255.255. 255.0 allows for close to 256 unique hosts within the network (since not all 256 IP addresses can be used). … This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256). The largest Class A networks use a subnet mask of 255.0.
