There is no way you can perform the update. For several reasons:
1. you can perform DNS Update for a IP address obtained from DHCPv6 only 
(i.e. DNS Update works for stateful DHCP only)
2. Client has to send its name to server as a hint. If server has this
name on a list of possible names to assign (and the name is available), 
then it will be assigned to the client.

That is how DNS Updates are implemented in the dibbler. I suppose it 
should be possible to obtain hostname from the system (right now it is 
configured manualy in client.conf). That seems like a feature to

Domain name is stored in client-IfaceMgr.xml in /var/lib/dibbler (Linux) 
or directory where dibbler is installed. Unfortunately, there is no way to 
execute script after the domain name is retrieved.

Hope that helps,
