DHCP Snooping
The addresses assigned to DHCP clients on insecure ports can be carefully
controlled using the dynamic bindings registered with DHCP Snooping (or using
the static bindings configured with IP Source Guard). DHCP snooping allows a
switch to protect a network from rogue DHCP servers or other devices which send
port-related information to a DHCP server. This information can be useful in
tracking an IP address back to a physical port.
