This document is intended to introduce ARP protocol, ARP spoofing attacks, and the countermeasure devised by D-Link written into the "Sender H/W Address" and its IP address will be written into the "Sender Protocol - D-Link DES-3028 | Product Manual - Page 301
will flood the frame to all ports except the source port, port 1 (see Figure -2). Figure - 2 When the switch floods the frame of the ARP request to the network, all PCs will receive and examine the frame but only PC B will reply to the query because the destination IP matches (see Figure-3).

, modify the traffic, or stop the traffic altogether (known as a Denial of Service - DoS attack). The principle of ARP spoofing is to send the fake, or random MAC addresses with the IP address of another node (such as the default gateway). Any traffic meant for that IP address would be mistakenly re - D-Link DES-3028 | Product Manual - Page 304
attack today can be done by associating a nonexistent or any specified MAC address to the IP address of the network's default gateway. The malicious attacker only needs to broadcast ONE Gratuitous ARP to the network claiming it be then sniffed by the hacker without the users knowledge.

(In this example, it is the gateway's ARP.) 2. The switch will deny all other ARP packets which claim they are from the gateway's IP. When calculating packet offset on DES-3028 series, remember that even though a port is an untagged port, the packet will add additional 4 bytes of 802.1Q header (TCI - D-Link DES-3028 | Product Manual - Page 306
