Get the IP address of one of your classmates. Send a ping to this address as in ping 111.222.111.222 substituting with the actual IP address.

Use wireshark to find the MAC address of that classmate's computer network interface. Send me a screenshot from wireshark.

Same exercise as above, but send the ping to www.cnn.org. What is the MAC- and IP-addresses of the network interface passing your message on?
