There is no owned > record data in the question section (and the entries in the question > section are not RRs). Oddly, "owner name" is correct here. From RFC 1035, Section 3.2.1 which describes the format of resource records: All RRs have the same top level format shown below: 1 1 1 1 1 1 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | | / / / NAME / | | +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | TYPE | +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ . . . where: NAME an owner name, i.e., the name of the node to which this resource record pertains. . . . And I think that Stephane's new definition text is a good addition to the draft. --Paul Hoffman
