Yes, that's exactly the point: We have two types of client definitions: 
1) hosts and 2) classes.  The big question is: How do allow/deny 
statements work when used simultaneously with clients of types 1) and/or 
2)?

Chris has clarified 
(https://lists.isc.org/pipermail/dhcp-users/2014-February/017625.html) 
the case of 2) only.

Thanks,
Ole
