A typical Ethernet frame. A spoofed frame could have faked source
MAC addresses to trick devices on the network.
ARP Spoofing is a technique used by crackers in order to sniff frames on a switched LAN or stop the traffic on the LAN.
The principle of ARP spoofing is to send fake ARP requests to the LAN. The frame contains a different MAC address than the one belonging to the sender. This confuses network devices and as a result frames intended for one machine can be mistakenly sent to another (allowing the packets to be sniffed) or even sent to an unreachable host.
Using IPv6, IPSec and static ARP records are methods to defend against ARP spoofing attacks.
This type of attack is also known as ARP poisoning.
