Appendix B

ARP Packet Content ACL

Address Resolution Protocol (ARP) is the standard method for finding a host's hardware address (MAC address) when only its IP
address is known. This protocol is vulnerable that crackers can spoof the IP and MAC information in the ARP packets to attack a
LAN (known as ARP spoofing). This document is intended to introduce ARP protocol, ARP spoofing attacks, and the
countermeasure brought by D-Link's switches to throttle the ARP spoofing attack.

How Address Resolution Protocol works

In the process of ARP, PC A will, firstly, issue an ARP request to query PC B’s MAC address. The network structure is shown in
Figure-1.

441

Figure-1

At the mean time, PC A’s MAC address will be written into the “Sender H/W Address” and its IP address will be written into the
“Sender Protocol Address” in ARP payload. As PC B’s MAC address is unknown, the “Target H/W Address” will be “00-00-00-00-
00-00” while PC B’s IP address will be written into the “Target Protocol Address”, shown in Table-1.

Table -1 (ARP Payload)

The ARP request will be encapsulated into Ethernet frame and sent out. As can be seen in Table-2, the “Source Address” in the
Ethernet frame will be PC A’s MAC address. Since ARP request is sent via broadcast, the “Destination address” is in a format of
Ethernet broadcast (FF-FF-FF-FF-FF-FF).
