The subnet mask is 24 bits, and the value is 192.168.1, or we can say 192.168.1.1/24. The total number of network ids possible is 0xFFFFFF in the case of the C class IP address. Which a considerable amount. Subnetting gives an opportunity of dividing the broad range into smaller ones. In our example, the subnet mask is 192.168.1.1/24.

In IPv6, the network prefix performs a similar function as the subnet mask in IPv4, with the prefix length representing the number of bits in the address. Prior to the introduction of CIDR, IPv4 network prefixes could be directly obtained from the IP address based on the class (A, B, or C, which vary based on the range of IP addresses they include) of the address and the network mask.

Subnet Mask is a 32 bit number that identifies the subnet to which an IP Address belongs. How to calculate Subnet Mask? Subnet Mask for IP Address is calculated by setting all the bits reserved for network ID and subnet ID to 1 and all the bits reserved for Host ID to 0.

IPv6 ,Subnet, Cheat Sheet. IPv6 is a complete and different animal as far as subnetting goes. Please note the yellow rows as each has special common use or notes. If there is nothing in the "Amount of a /64" column that means it is to miniscule or to massive to justify calculation. Not much is the same with IPv6 compared to IPv4.

Using subnetting, the same group of connected computers can work as independent two or more networks. Each group has a separate network id. A subnet mask is the value for getting a network id from the Ip address. Subnetting creates two or more separate broadcast network, which reduces network load and provides more security to the network users.

Subnet masks are composed of some number of 1 bits followed by enough 0 bits to form a 32-bit value, where the bit positions with a 1 correspond with the bit positions in the IP address that are part of the NET_ID. With classful addressing, then, the subnet mask will have 8, 16, or 24 one bits for Class A, B, and C addresses, respectively.
