First of all please read up on how IPv6 works. Then read up on how DHCP
works in an IPv6 environment. It's clear from your question that you do not
yet fully understand either of these.

You do not specify either the gateway (this is discovered automatically
from the RS/RA) or subnet mask (for the most part all client subnets should
be /64, again either discovered from the RS/RA or the OS assumes /64) in

So the remaining options you want are (but will depend on the client as to
whether they use them):
dhcp6.name-servers - comma separated IPv6 address(es)
dhcp6.sntp-servers - comma separated IPv6 address(es)

Ensure you have the correct RA flags set on your router to allow DHCP on
the IPv6 network.
