I'm thinking DHCP Snooping on switches that supports it. By making all the user port untrusted, the true DHCP server and DHCP Relay Agent trusted ports. Typically, the trusted ports are used to reach a DHCP server or relay agent.

So, a DHCP response from an untrusted port will cause that bogus DHCP server to not act as DHCP server.
