RBR850 IPv6 Support
Hello, Our ISP has recently enabled dual stack IPv4/IPv6 across it's network. This has led me to configure and start looking at the Orbi configuration for IPv6 to try and mirror what we have avai...
(I have a suspicion that my understanding of networking is not up to this task, but what the heck....)
I have implemented Pi-hole DNS servers on my Orbi and use their private IPv4 addresses in the Orbi DNS configuration.
Would IPv6 not be similar: i.e. use the fe80 Link Local addresses of the Pi-hole servers in the Orbi DNS configuration.
Orbi is going to give out its own IP address as the DNS, so all that matters is that the Orbi be able to find the Pi-holes on the local network.
The fact that the Orbi public IP changes from time to time never enters into the situation.
What am I missing?
Thankyou for responding, I appreciate it.
The Orbi interface will not allow me to put in a link local address. It returns an error stating that it must be a global unicast address. I have attached a screen shot of the error.(I knew this was 'over my head')
I have two Pi-hole DNS servers, and entered the Link Local IPv6 addresses for them into my Orbi RBR50.
(See attached screen shot)
Got no error pop-up.
Logically, I think, "why should the Orbi care where the user directs DNS queries?" Private IP addresses are OK. Why not Link Local IP addresses?
So, my (ancient) Orbi will take Link Local IPv6 addresses for DNS.
It is a more complicated task to verify that IPv6 DNS requests get sent to my two Pi-holes. I think (hope) that I have my PC set to use the Orbi DNS and my "ping -6" command forces IPv6 for DNS. But, I am not seeing the DNS requests in the dashboard of my Pi-holes. Grrrr.
Thankyou again for your response.
Our of interest did you configure these via the mobile application or the web page?
I have investigated the error returned via the popup and it appears to be done in front end javascript. Currently looking at posting directly to the CGI to bypass the JS and see if it will take the setting.
