DHCPv6 not updating DDNS

[Glenn Satchell]

Hi Scott

I don't see a ddns-update-style statement anywhere. The default value is
"none", which means - you guessed it - no ddns updates :)

      ddns-update-style style;

       The style parameter must be  one  of  ad-hoc,  interim  or
       none.   The ddns-update-style statement is only meaningful
       in the outer scope - it is evaluated  once  after  reading
       the  dhcpd.conf  file,  rather  than each time a client is
       assigned an IP address, so there is no  way  to  use  dif-
       ferent  DNS  update  styles  for  different  clients.  The
       default is none.

regards,
