ARP Packet Injection Programming

ARP is one of the most important protocols needed for LAN communication. Unfortunately as it is not encrypted, it is easy to spoof ARP packets using packet injection.

We will then use Wireshark to verify that the packet has actually been sent out into the network correctly.
