Providing calculating for the first address, total number of addresses available in the block and the correct prefix for each subnet (2 marks).

Question 3 – Network Tools (Windows) (4 marks)

Often the best way to gain an initial familiarity with network tools is to simply use them, at a basic level in exploratory mode as suggested in some of the tutorial exercises. Ipconfig and Route are included in Windows, while Wireshark is free to download and install. Explore all three tools including introductory level readings, then complete the questions following.

3A: Wireshark

A wireshark scan has produced a packet capture, saved to a file named wireshark_pcap01.pcapng and available on the Unit website. Download the file and open it in Wireshark, then answer these questions about the scan:

  1. View Frame 5: Was this packet from client to server, or server to client? What type of application was responsible for this ACK message? Give reasons for your answers (essential). (1 mark)

  1. View Frames 446-447 (hint:use Go): Describe the details of what is happening here (use Protocol and Info columns). What is your best guess about what is happening between the source and destination devices based on the data captured? (1 mark)

3B: ROUTE PRINT

A “ROUTE PRINT” command in Windows displays the computer’s routing table as shown in the screenshot below. Type ‘route print’ in a Windows CMD window to take a look at the routing table in your own computer; study the information available, then answer the following question in your own words. NOTE: for safety do not use “run as administrator” when opening a CMD window.

Sample Windows routing table:

Question 3B: Briefly discuss in your own words each of the five columns ‘Network

Destination’, ‘Netmask’, ‘Gateway’, ‘Interface’, and ‘Metric’ and their contents. Be sure to explain which table entry is the default route, what are the ‘on-link’ entries, and the numbers under Metric. (1 mark)

3C: IPCONFIG

Using the CMD window, type ‘route print’ again, but this time notice the ‘Interface List’ above the main table. Next, type ‘ipconfig’ to see the basic configuration items for your computer’s interfaces. Type ‘ipconfig /all’ to see more detailed configuration data. Do further reading as necessary, then answer the following question in your own words:

Question 3C: Define ‘Interface’, then using the route print and ipconfig output, identify the main network and wi-fi adapter (two adapters) in your system and briefly summarize their configuration. (1 mark)
