I am also trying to setup the IPV6 DNS server on a netgear R7000 nighthawk. The problem is that I have 8 fields separated by colons per DNS server in the router config. I only see 4 sets of numbers (5 if I leave the one between the double colons blank)?
How do I enter the numbers into those fields?
2606:4700:4700:: 1111 and 2606:4700:4700:: 1001
