An IP addresshas two components, the network address and the host address. A subnet mask separates the IP address into the network and host addresses (). Subnettingfurther divides the host part ofan IP address into a subnet and host address () if additional subnetwork is needed. Use theSubnet Calculatorto retrieve subnetwork information from IP address and Subnet Mask. It is called asubnet mask because it is used to identify network address of an IP address by perfoming a bitwise AND operation on the netmask.A Subnet mask is a 32-bit number that masks an IP address, and divides the IP address into network address and host address. Subnet Mask is made by setting network bits to all "1"s and setting host bits to all "0"s. Within a given network, two host addresses are reserved for special purpose, and cannot be assigned to hosts. The "0" address is assigned a network address and "255" is assigned to a broadcast address, and they cannot be assigned to hosts.Examples of commonly used netmasks for classed networksare 8-bits (Class A), 16-bits (Class B) and 24-bits (Class C),

Subnet Masks
With the advent of subnetting, one can no longer rely on the definition of the IP address classes to determine the network ID in the IP address. A new value is needed to define which part of the IP address is the network ID and which part is the host ID regardless of whether class-based or subnetted network IDs are being used.
RFC 950 defines the use of a subnet mask (also referred to as an address mask) as a 32-bit value that is used to distinguish the network ID from the host ID in an arbitrary IP address. The bits of the subnet mask are defined as follows:
