How many bits are in a subnet mask

WebJun 30, 2024 · IPv4 had a subnet mask (dotted quad notation) that was later replaced by CIDR masking. IPv6 doesn’t have a subnet mask but instead calls it a Prefix Length, often shortened to “Prefix”. Prefix length and CIDR masking work similarly; The prefix length denotes how many bits of the address define the network in which it exists. Web1 day ago · Convert the subnet mask or prefix length from decimal notation into binary. Count the number of zeros in the binary notation. This will tell you how many host bits are available for each subnet. Calculate 2 raised to the power of the number of host bits minus 2 (this is because two addresses are reserved for the network and broadcast addresses).
