<pre>I think it was a number of issues, zone certainly pointed dhcpd to the correct dns server, I monkeyed a bit with ddns-* particularly when I found that I was able to get the forward record but the reverse came up as 16.36.57.10.106.36.57.10.in-addr.arpa.<o:p></o:p></pre>

<pre>I've currently got it set to "in-addr.arpa." but that means that all reverse records from all different zones will end up in the same PTR file. Is that typical or is there a better way do to this?<o:p></o:p></pre>

<pre>Do you have zone statements in your dhcpd.conf ?<o:p></o:p></pre>
<pre>If not using secure updates, you can just rely on having the zones correctly set up (correct SOA record) and dhcpd will find the master server from the SOA record. But since you are using signed updates, you must specify zones in dhcpd.conf - the syntax is *almost*, but not quite, identical to that in named.conf.<o:p></o:p></pre>
