<p class="MsoNormal">Hi @all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am using PowerDNS Authoritative server with the postgresql backend. I am curious if there are any plans on the server side to support QNAME minimization.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When querying with QNAME minimization on strict, the authoritative server is queried for entry.sample.zone and returns NXDOMAIN. This causes the query to fail. From my understanding, if the server returned NODATA instead the query should
continue with level.entry.sample.zone (and so on) until the proper target is reached.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This does allow fall backs in some implementations, but it seems when DNSSEC is enabled on a zone it will not fall back with some resolvers (unbound is a good example).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks!<o:p></o:p></p>
