Destination MAC – Checks the destination MAC address in the Ethernet header against the target MAC address in the ARP body.
Source MAC – Checks the source MAC address in the Ethernet header against the sender MAC address in the ARP body.
IP address – Checks the ARP body for invalid and unexpected IP addresses including addresses 0.0.0.0, 255.255.255.255, and all IP multicast addresses.
