Work through the ARP Request and Response sections on pages 88/89.
IP
Capture an IP packet (use a precaptured one from lotsofweb.pcap if you need to)
Fill in the information in Figure 6-9.
Use ip_frag_source.pcap to work through the fragmentation section on page 95. Reflect of the differences between fragmentation at the IP level and at the Ethernet level. (300 words)

Capture a TCP packet
Inspect the the ports associated with the packet, indicating what application is associated with that port
UDP

Fill in the information in table 6-27. (Reflect on why this information is so much less than for TCP)
Inspect the the ports associated with the packet, indicating what application is associated with that port
