Yes. Though it depends on what the question was, which server you ask and what data it has. RFC2308 lists some examples of valid NXDOMAIN/NODATA responses containing no SOA record. > It would break negative cacheing. So what? It's not compulsory to implement or support that. Which would of course be a Bad Idea. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
