Create standards for IP address assignments within each subnet range. For example:

Two very important factors that will lead to the determination of which private address block is required, are the number of subnets required and the maximum number of hosts needed per subnet. Each of these address blocks will allow you to appropriately allocate hosts based on the given size of a network and its required hosts currently and in the near future. Your IP space requirements will determine the range or ranges of hosts you implement.

In the upcoming examples you will see subnetting based on address blocks that have subnet masks of,, and
