Procedure

1. Open wireshark, ping google (8.8.8.8) and analyze the request.
2. What is the source MAC address? What is the destination MAC address?
3. Does the source MAC address look familiar from prior labs? Do you think it is the Google Server's MAC address?
4. Ping another system's IP on the LAN. Capture this ping in Wireshark.
5. What are the source and destination MACs in the ping reply
6. What is your partner's MAC address?
7. Does the MAC address match the address from you traffic capture? If not - what do you think happened?
8. Now both partners need to ping each other and both need to capture these pings on Wireshark.
9. On your workstation, what is the source and destination MACs from the pings?
10. On your partner's workstation, what is the source and destination MACs from the pings? Why are these different?
