It seems that since the widnows 10 1607 (14393.51) release, windows does not pick up ipv6 dns servers from dhcpv6. I've seen this in my network, but I was wondering if this is a general issue.
I have noticed that on all my Windows 10 machines with the Anniversary Update, they no longer receive IPv6 DNS from DHCPv6 servers if network is configured for Stateless DHCP (Managed Flag unset, Other Flag Set in RA). They receive IPv6 information correctly if the network is configured for Stateful DHCP.https://social.technet.microsoft.com/Forums/windows/en-US/b16e7d78-e390-4ada-a24b-3ccba60fa571/no-ipv6-dns-statelessdhcp-since-windows-10-anniversary-update?forum=win10itpronetworking
It isn't just you. DNS servers aren't picked up after the AU via either RDNSS (which never worked) or stateless DHCPv6. Several others have made the same observation - something is clearly broken.
