ARP rate limiting restricts the number of ARP packets per second to mitigate flooding but does not validate IP-to-MAC address mappings.

DHCP snooping builds the binding table that DAI relies on, but it does not itself inspect or validate ARP packets.

Dynamic ARP Inspection intercepts, logs, and discards ARP packets with invalid IP-to-MAC address bindings by comparing them against the DHCP snooping binding table. It operates at the data-link layer on switch ports and distinguishes trusted from untrusted interfaces, ensuring only legitimate ARP responses propagate through the network.

IP Source Guard filters traffic based on IP source address using the DHCP snooping table but does not inspect ARP message content or bindings.
