In the previous videos, we have described and configured DHCP Snooping, and in this one, I'm going to show you how to block manually configured IPs in a cisco switching environment using dynamic ARP inspection.
Manually configured IP is dangerous if not controlled because it can create a man-in-the-middle attack or bring down the entire subnet accidentally, for example if someone sets the gateway IP address as their own IP address on a computer.
That's why it is important to have control and don't allow manually configured IP addresses.
