1.  You have a small business that is divided into 3 departments:  Accounting, Sales, and Administration.  These departments have the following number of devices (computers, printers, etc.):  Accounting-31, Sales-28, and Administration-13.  Using a class C private network , subnet the network so that each department will have their own subnet.  You must show/explain how you arrived at your conclusion and also show the following:  All available device addresses for each department, the broadcast address for each department, and the network address for each department.  Also, determine how many "wasted" (not usable) addresses resulted from your subnetting (enumerate them).

2.  After two years, business has boomed.  Accounting now has 37 computers, Sales 35, and Administration 24.  In addition, you have added a Shipping department and a Production department.  Shipping has 13 computers and Production has 21.  Using a class B private network , rework the subnetting for the business with the same information (deliverables) as in problem 1.

3.  Finally, your company is purchased and merged with a larger company.  The new company has the following needs:  Main office-1211 computers, Muncie branch office-917 computers, Indianapolis plant-2014 computers, and the Mt. Vernon distribution center 945 computers.  Using a class A private network , subnet so that each site has its own network to handle its current computer requirements plus a 20% cushion for future growth and provide the same information (deliverables) as in problems 1 and 2.

NOTE:  We will assume, for the purposes of this assignment, that you are using all Cisco equipment and that all equipment has been configured with the ip subnet zero Cisco IOS command.  Accordingly, you may use subnet zero and also the all-ones subnet.
