NAME

        SV_RFC1034_4_3_3_not_applied_wildcard - Wildcards is not applied case

VERIFICATION POINTS

        Verify that a NUT does not apply Wildcard RRs.

        Wildcard RRs do not apply:

           - When the query is in another zone.  That is, delegation cancels
             the wildcard defaults.

           - When the query name or a name between the wildcard domain and
             the query name is know to exist.

TARGET

        Authoritative Server
