I'm a bit confused because you appear to have two named.conf
files, one for<br>
IPv4 and one for IPv6. I only have one DNS server which handles
both IPv4<br>
and IPv6. My DHCP and DNS services run on the same machine. I
have:<br>
<font color="#993300"><tt>key DHCP_UPDATER {
algorithm hmac-md5; secret <the_secret>; };</tt><tt><br>
</tt><tt>zone lan.example.com. { primary
127.0.0.1; key DHCP_UPDATER; }</tt><tt><br>
</tt></font>Note the 127.0.0.1 for both IPv4 and IPv6.<br>

<font face="Droid Serif">Yes, I do have two config files, but only
for comparison/testing purposes. I actually only need DHCPv6, but
because I couldn't get it to work, I wanted to see if I could get
it to work with IPv4 (which I can). So when I use the IPv4 config
file, I run dhcpd with -4 and when I run the IPv6 config file I
run dhcpd with -6. So when you say you have both IPv4 and 6
running on the same server, do you mean two instances of dhcpd on
the same server? It was my understanding that you can't run the
same instance of dhcpd for both IPv4 and 6. The man page seems to
indicate this:<br>
<br>
-4 Run as a DHCP server. This is the default and cannot be
combined with -6.<br>

I did have to set (in both dhcpd.conf):<br>
<font color="#993300"><tt>update-conflict-detection off;</tt><tt><br>
</tt></font>to enable both DHCPs to update the DNS.<br>

I'll give this option a try, thanks.<br>
