<p>Hello, I am starting to setup and learn DHCPv6. I have things working somewhat well, except for the fact that I cannot get Forward DDNS updates to work. Reverse works great, and the machines that fail to update the Forward map are receiving a valid IPv6 address from the range6 declaration in my dhcpd.conf file.<br>
<br>
Here is the error I am getting in /var/log/messages :<br>
<br>
