<p>Given the zone:</p>
|
|
|
|
<pre><code>subdomain IN NS nameserver
|
|
nameserver IN CNAME nameserver.otherserver
|
|
</code></pre>
|
|
|
|
<p>in a BIND server that is both recursive and authoritative, requests without RD (recursion desired) return the NS record, while requests with RD return SERVFAIL. Changing it to:</p>
|
|
|
|
<pre><code>subdomain IN NS nameserver.otherserver
|
|
</code></pre>
|
|
|
|
<p>fixes the problem, though both resolution trees are perfectly valid.</p>
