Figure1 below shows the allocated space given by the ISP and how it is displayed in binary. The first thing to Figure out is whether the amount of addresses allocated for the organization is enough to meet the requirements with it. Each of the different departments requires at least 40 different usable addresses and at least 10 extra addresses allocated for future growth. The address space that has been allocated to the University by their Internet Service Provider (ISP) is 172.16.0.0/23. Each of the different departments needs to be separate and have their own IP address space. As the university operates strictly online, its main campus location includes only a single physical building with 4 floors and 8 total departments: Administration, Admissions, Financial Aid, Business school, Liberal Arts school, Internet Technology school, Science school, and History school. The Acme University is planning to deploy an IP network in their main campus location and it wants to ensure that it is developed in a way to ensure that easy growth is possible. The math that is required to come up with each of the networks will be covered and visually displayed to ensure that the concepts are clearer to understand.


In an effort to take the concepts that were covered in “IP Subnetting Basics” and “Advanced IPv4 Subnet Concepts and Examples” and put them to use in a more real world example, this article will put together an IP addressing scheme based on the requirements of an imaginary organization.
