However, I noticed that I have to enter DNS servers manually. Is there a way to set up dns servers for clients automatically without using DHCPv6? I know there are extensions that support rDNS servers&  DNS search domains via the stateless protocol but is there a way I can also send DNS server info?

I stopped needing radvd 2 years ago when my new gateway router gave me 
the needed functionality.

But here is an example from my radvd.conf:

interface eth1.16
{
         AdvSendAdvert on;
         MinRtrAdvInterval 3;
         MaxRtrAdvInterval 10;
         prefix 2607:f4b8:3:3::/64
         {
                 AdvOnLink off;
                 AdvAutonomous on;
                 AdvRouterAddr on;
                 AdvPreferredLifetime 20;
                 AdvValidLifetime 30;
         };
         route ::/0
         {
         };
};

Note the AdvRouterAddr line.  This gets the interface address of the 
router being sent to the clients

My research on it seems to confirm this but I just want someone else whi has had real world experience with this.
