[kea-dev] boot-unknown-clients equivalent?

[Peter Davies]

Hi Philip,

   If you only employ host reservations, then the built-in "KNOW" class may be use to restrict clients.

For example:

    "client-classes": [{
            "name": "DROP",
            "test": "not member('KNOWN')"} ],

...

I advise caution, as this will drop all packet that are not associated with a host reservation.

/Peter
