This Challenge Lab should be done in groups. You will need at least three computers, patch cables, and a switch for each group. The computers can run Windows, Linux, or Mac OS X. You should build a network, configure TCP/IP on each computer, and test communication among the computers. Here are the requirements: 1. Use a TCP/IP Class A address for the IP addresses with an appropriate subnet mask. 2. Test communication among all computers. 3. Answer the following questions.

Discussion Questions a. What IP network address did you use? b. What subnet mask did you use? c. What command did you use to test communication? d. What would you need to add to the network to gain access to other networks, including the Internet? How would your TCP/IP configuration change?
