The idea and its mitigation for dhcpd is discussed in AA-00211 article in KB. The question is how to handle that in Kea.

It seems the easiest way is to introduce a class with special meaning, e.g. "drop". If packet is classified to that class, it gets dropped immediately.

Admin would take advantage of that capability by either defining a class (and ban whole group of devices at once) or could define host reservations (without any addresses) and "client-class": "drop".
