Description (partial)

The CLI (nrcmd) syntax for the zone <i>name</i> command implied that it supported any resource record class, however it only supports the IN class. The syntax has been corrected to replace the optional class with IN instead.

The CLI (nrcmd) syntax used RRType-<i>number</i> for unknown resource record types, but this is not consistent with RFC 3597 which uses TYPE<i>number</i>.

Network Registrar used <i>number</i> for unknown class types, but this is not consistent with RFC 3597 which uses CLASS<i>number</i>.

These situation should be extremely rare as using unknown RR types or unknown RR classes is unusual.
