Unable to change the IPv6 IP or DNS

Hello!

Hope you are well. I'll be glad to assist you.

The IPv6 address is a parameter that cannot be modified, as it is a unique address assigned to you by your internet provider.

The DNS server address can be modified from the advanced network configuration options.

Best regards!

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.

Try Changing the DNS. I use Google DNS.

1. From the Xbox One home screen, go to Settings > Network > Advanced settings > DNS settings > Manual. (If Settings doesn't appear on the home screen, select My Games & Apps, then Settings.)
2. From there, enter the Primary DNS as "8.8.8.8" and the Secondary DNS as "8.8.4.4"

If you want to change your current DNS server to Google Public DNS, you will need to change your IP addresses to 8.8.8.8 and 8.8.4.4. (IPV4)

Google Public DNS also provides support for IPv6 connectivity so if you meet the necessary requirements for setting up an IPv6 connection, you will have to alter your IP address accordingly.

For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844

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.
