Both in my lab testing and on real installation I saw that, after a dcpromo (done via "Server Manager" on Windows 2016), a loopback IPv6 address is automatically added on the interface DNS settings (ie: ::1 as primary and sole DNS).
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).
It is my understanding that, when having multiple domain controllers, it is never advised to use the loopback address as the primary DNS address.
So, my question is: is it correct to remove the IPv6 DNS loopback address from the interface DNS settings?
