Security Implications and ARP Spoofing The trust-based nature of ARP makes it a prime target for network attacks. If the mapping is not present, the device broadcasts an ARP request packet containing the target IP address across the local network segment.

Without this process, data frames could not traverse Ethernet networks, rendering IP addresses useless for direct device communication. How ARP Functions on Cisco Devices When a Cisco device needs to send a frame to a host on the same local network, it checks its ARP cache to map the destination IP address to a MAC address.
This redirection allows the attacker to intercept, modify, or block data traffic without the victims' knowledge. Duplicate IP addresses on the network cause confusion in the ARP cache, leading to intermittent connectivity as the MAC address flips between devices.
