for each host, if I understand correctly. Please correct me if I am 
wrong.  I am under the impression that the use of wildcards is filtered 
by looking for a corresponding SOA and thus if we appended RRs to the 
.mp zone file then we would still end up with no SOA, is this correct? 
Perhaps you can briefly explain how ddns would help?
