IPv6 DNS Option

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!

Ok I have set DNS route to Cloudfare and 2nd test I got 287/235 so it is marginally better. Xbox does not have option to set DNS for IPV6 but it is an option. Now my question is with that said should I kick my Box out of DMZ? and Secondly IPV6 since Xbox is unable to use alternate DNS should I disable it throught the router? Cloudfare is marginally better than Auto or Google DNS.

Thanks

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.

Hi guys,

Thanks for the responses, managed to fix it.

My router had assigned my Xbox One a IPv6 primary DNS even though the router itself had IPv6 connections disabled. I was unable to change the DNS setting on the console as it kept reverting to the IPv6 DNS so had to go into my router using TelNet and make
a few changes using that to redisable the IPv6.

Xbox One now has the IPv4 DNS servers and is now working much quicker.

I've got IPV6 DNS and never get disconnected while online gaming. I think it would not work at all if it really came from ipv6 dns issue. Your disconnects should come from elsewhere?
