Re: Strange behavior from resolvers?
RFC 2308 enumerates the negative response types. It did not invent new ones (AA=0 aside). They all existed in RFC 103[45] as did referral. RFC 2308 just pointed out easy mistakes to make. If a nameserver does not understand these response enumerated in RFC 2308 it is not RFC 103[45] compliant. If a nameserver generates the wrong response, as in this case when it generated a referral rather than one of the possible NODATA responses, it is not RFC 103[45] compliant.
