I think the intent of the text is that an name is only used by the protocol in RFC 2136. It is referenced as a concept in RFC 1996, but not used by the protocol. But I agree that the text above is confusing, and if that's the intent then it should be rewritten. > > Secondly: can someone please explain to me why the idea of a > "primary master" where the zone data originates from and where > updates are performed is considered archaic? > That doesn't make sense to me either. Perhaps somebody thinks that Update messages are no longer in use?
