Does the source MAC address look familiar from prior labs? Do you think it is the Google Server's MAC address?

Yes, the MAC address is the address of the default gateway. It is not the Google Server MAC address because we cannot access Google's LAN so we can't see the server MAC address.

Part 2: Examine both sides of a ping

  1. From your workstation, ping your partner's IP and make sure you get a response

Pinging Lily's workstation

  1. On your workstation analyze the capture.

What are the source and destination MACs in the ping reply

source: 00:0c:29:6f:4e:25

Destination: 00:0c:29:6c:b9:7e

What is your partner's MAC address?

00:0c:29:6c:b9:7e

Does the MAC address match the address from your traffic capture?

My MAC address is the same, but the address that I am pinging now has a different MAC because it's has a different destination.

Part 3: Capture both sides of the ping request

On your workstation, what is the source and destination MACs from the pings?

Source: 00:0c:29:6f:4e:25

Destination: 00:0c:29:6c:b9:7e
