IPv6 DNS manual changes on Xbox...

I have tried the same thing manual DNS setup does nothing. In my case the IPv6 DNS names are displayed in the network configuration (even though I am configuring IPv4) and there is no way to change them. I have setup IPv4 manually but the DNS is still
taking DHCP IPv6.

Ok, it looks like the DNS is defaulting to IPv6. The xbox will not let me change the DNS manually (seems to be a bug). I tried disabling ipv6 in my router but that basically broke my internet so it's not a viable option. PLEASE FIX THIS MICROSOFT!

I had same problem but it has fixed now.

In my case, Xbox One network setting about DNS showed IPv6 address, although I didn't use IPv6 connection.

I tried to change the DNS address manually in Xbox settings, but it wasn't changed correctly . So I changed my home network rooter settings about DNS from "Auto" to "Manual IP"( dns address provided by your internet provider) .

Then, backward compatibility was working well, my Xbox 360 profile download started.

Only way to get around it for now that I know of - don't direct connect to your cable modem but instead place a router capable of working with IPV4 and IPV6 and then change the DNS settings for the WAN ports there.

I have comcast myself and yes their IPV6 DNS servers are not ready for prime time. Test performed using theirs mostly fail, while using googles Public iPV6 DNS servers always pass.

So, what I did - though the router will receive it's Public IP's (IPV4 and IPV6) and the DNS Servers to use. I instead changed the DNS settings from Auto to Manual - Manually adding Googles DNS Servers for both IPV4 and IPV6 but leaving the Actual Addressing
set to auto for both IPV4 and IPV6.

Thus: Anything DHCPing from my router (which acts as a DNS Forwarder) will receive and IP Address for my network along with the Routers IP Address as the DNS Server. Noted on my XBOX ONE that my Primary DNS Server is in an IPV6 Format and it's set to my
Routers Local IP Address. So what happens now AND DNS Requests will now pass DNS thru the router to what it was told to use as DNS servers which are now Googles Public DNS servers for both IPV4 and IPV6.

Problem solved.
