So DNS setup is just simple DNS setup (but on a Windows 2008 R2 server to support IPv6 addressing) For the first step, build a Windows 2008 R2 server and give it an IPv6 address like you did above.
This IPv6 DNS address even take precedence over anything configured in the IPv4 DNS panel. This is confirmed both by ipconfig /all (which lists the IPV6 ::1 address as the first one) and by nslookup (which asks the ::1 server to resolve). Find the area of configuration in which DNS server settings are specified and replace those addresses with the Cisco Umbrella IP addresses; Save your changes and exit your router’s configuration interface. Flush your DNS cache. You can use either the IPV4 or IPv6 DNS addresses as your primary and secondary DNS servers. DNS remains unchanged, except for the addition of the AAAA record that holds IPv6 addresses; AAAA records are retrievable via IPv4 as well. DHCP functions the same, but the specifics are adapted for IPv6 and to disambiguate, it is known as DHCPv6 ; there is a separate RFC: RFC-3315 . All devices get a routable IPv6 address these days because of the large address space. I cannot modify the Upstream DNS servers on my PiHole settings page to include, for example, Google's IPv6 servers. I don't know why. IPv6 testing sites show that I can reach them via IPv6. Jun 24, 2016 · DNS - DDNS with DHCPv4 and DHCPv6. This page describes using and configuring DHCP for IPv4 (DHCPv4) and IPv6 (DHCPv6) to enable automatic updating of both the forward and reverse mapping zone file. While this is extremely useful for IPv4 it is practically essential for IPv6. I am trying to perform the same benchmark for IPv6 DNS servers as the the applications listed in my post do for IPv4 DNS servers. I also do not see in the application or via google search an option to enable IPv6 benchmark with Googles namebench application. BUT, it does not work for IPv6, only the first IPv6 DNS Server appear at my resolv.conf, look: "dns-nameservers 2001:4860:4860::8844 2001:4860:4860::8888" But then, my resolv.conf remain only with the first one: nameserver 2001:4860:4860::8844 Apparently, Ubuntu (resolvconf / ifupdown) is ignoring the second DNS Name Server, so, how to fix it?!
