You work as a network engineer in a company and you were asked to design a small network. The company plans to have $8$departments. Currently, $6$ departments are on business. The company asked you to build a network that allows the $6$ departments to communicate. The network should be easily expanded to cover all the $8$ departments in the future.

Assume that you decide to use Private class B $[192\mathrm{.}168\mathrm{.}10\mathrm{.}0/24]$ for the company IP addressing scheme.
