IP Address Exercise 1:
Contoso Inc. is a small company with two departments (Marketing and Sales). In order to
take advantage of the growing global market, the company decided to setup a commercial
website. For that, Contoso Inc. applied for a domain name and a network part to use for
assigning IP addresses to its existing server and workstations. The Registrar assigned the
Network Part 137.75 to the company. As the assistant of the network administrator at
Contoso Inc., you are responsible for assigning IP addresses to the company’s server and
workstations. Six workstations and the server are located in the Marketing department.
The other workstations are located in the Sales department. Based on your knowledge
about Network parts, Segment parts and Host parts, assign IP addresses so that we can
easily know the location of a computer based on its IP address.
