Explanation
DHCP spoofing occurs when an attacker attempts to respond to DHCP requests and trying to list themselves
(spoofs) as the default gateway or DNS server, hence, initiating a man in the middle attack. With that, it is
possible that they can intercept traffic from users before forwarding to the real gateway or perform DoS by
flooding the real DHCP server with request to choke ip address resources.
