Lab 2-2 Observing LAN Activity

Summary:

In this lab we used the ping tool and wireshark to observe what happens when you ping a device on the same lan and one not on the lan.

Summary of understanding:

  • I had no issues while completing this lab

I: Observe a simple capture - Ping the Default Gateway:

Record: What are the source and destination MAC addresses (Not IP Addresses)

Record: What are the source and destination MAC addresses

Question: What is the MAC address of your workstation's NIC? What is the MAC address of the Default Gateway Router interface (NIC)?

  • Default gateway mac:
    • bc:24:11:44:b7:c4
  • Workstation NIC:
    • bc:24:11:d4:5d:dc

II. Observe a simple capture - Ping outside LAN IP addresses:

  • Repeat the Wireshark capture of a ping - but this time use www.timeslive.co.za as the destination address.
  • What is the first IPv4 IP address from the site?
    23.201.56.20
  • Record: What are the source and destination MAC addresses
  • Answer: Compare the source/destination MAC address with the MAC addresses captured above.  Are they the same or different? Discuss why they are the same or different.
    • They are the same because it is still talking to the default gateway not the server directly.
