also use private network addresses for the advantage of making it easier for the organization to change their internet service provider without having to renumber their IP addresses and for added security. The use of a subnet would work as well. Subnetting will allow a network administrator to divide one physical network into smaller logical networks. It would also control the flow of traffic for security and efficiency. There is not an accurate mechanism that exists for assigning network or subnet
