NOTE: Address Resolution Protocol (ARP) is the standard for finding a
host's hardware address (MAC Address). However, ARP is vulnerable as
it can be easily spoofed and utilized to attack a LAN. For a more detailed
explanation on how ARP works and how to employ D-Link's advanced
unique Packet Content ACL to prevent ARP spoofing attack, please see
Appendix B, at the end of this manual.
