What is IP Subnetting:

Subnetting is the process of breaking down an IP network into smaller sub-networks called "subnets." Each subnet is a non-physical description (or ID) for a physical sub-network (usually a switched network of host containing a single router in a multi-router network).

There are two forms of subnet notation, standard notation and CIDR (Classless Internet Domain Routing) notation. Both versions of notation use a base address (or network address) to define the starting point of the network, such as 192.168.1.0. This means that the network begins at 192.168.1.0 and the first possible host IP address on this subnet would be 192.168.1.1.

In standard subnet mask notation, a four octet numeric value is used as with the base address, for example 255.255.255.0. The standard mask can be calculated by creating four binary values for each octet, and assigning the binary digit of .1. to the network potion, and assigning the binary digit of .0. to the network potion. In the example above this value would be 11111111.11111111.11111111.00000000. In combination with the base address you have a subnet definition, in this case the subnet in standard notation would be 192.168.1.0 255.255.255.0.

In CIDR notation, the number of 1.s in the binary version of the mask are counted from the left, and that number is appended to the end of the base address following a slash (/). In the example here the subnet would be listed in CIDR notation as 192.168.1.0/24.

How can I Compute the Maximum Number of Hosts for a Subnet Mask?

To compute the maximum number of hosts for a subnet mask, take two and raise it to the amount of bits allocated to the subnet (count the number of 0.s in the subnet mask binary value) and subtract two. You must subtract two from the resulting value because the first value in the IP address range (all 0s) is reserved for the network address, and the last value in the IP address range (all 1s) is reserved for the network broadcast address. For example, DSL networks commonly use 8 bits for their subnets. The amount of allowable hosts for such a DSL network could be computed by the following formula: max hosts = (2^8)-2 = 254 hosts.
