> Actually they aren't in conflict.   3.7.3 is saying "you need an authoritative name server on the local net."   3.7.4 is saying "if you want names to be resolved externally, one way to make this work would be to set up secondaries on external servers."  In fact, the solution that I've seen discussed recently is to have the master on the local network be a hidden master, so that the only published authoritative servers for the zone would be the secondaries.   But the architecture document rightly avoids prescribing that solution.

I think the confusion is caused by the use of the phrase "secondary resolving name service" in 3.7.4

Ted is (correctly, I think) taking the intent of that to mean a secondary _authoritative_ service, but us DNS heads think of "resolving" as what stubs and recursive servers do.

Tim - can you please clarify the intent?
