DHCP Snooping
What is DHCP Snooping?
  • Security

DHCP snooping makes a network more secure. There are no two ways about it: DHCP makes network configuration so much easier. This is especially the case in large networks, where devices are constantly changing and the manual assignment of IP addresses is a never-ending task. Yet by using DHCP to simplify the process, you do relinquish controls, and criminals can take advantage of this. By using...
