Assignment: Lab 3.1 ARP Observation

• Review ARP communication to and from my host system.

Problems Encountered:

• I could not find the ARP broadcast packet, but then I realized that I did not wipe the ARP cache of my host.

Helpful Commands:

ip -s -s neigh flush all

• This command will clear the ARP cache of your host kali system.

arp -n

• This command will show you previous devices you have communicated with.

Helpful Steps:

• If broadcast packet is not showing, clear ARP cache and ping client again.
• Make an ARP filter in Wireshark to monitor ARP traffic.

Final Ideas:

• I am now more aware of how layer two (MAC), and layer three (IP) addresses operate. I was able to use Wireshark to capture and analyze ARP requests and responses. This lab helped me understand how ARP is used between hosts on a LAN, recognize the basic flow of ARP, and identify the role of broadcasts with ARP.
