So the concern with returning an ordered RRset is that the set could be large: The intention is that each private site/network will have its own DNS server pair and that local recursors resolve all private zones from that local pair. So things like NS records would be in scope for the ordered RRset response. With more sites come more DNS pairs and therefore more NS records to be added to the RRset. Maybe I can limit a RRset response to the first X number of entries?

If sorting of replies won't suffice, please provide a hypothetical example of a couple of different clients & responses for an example RR. -- Grant. . . . unix || die
