How do I go about getting ipv6 instead of ipv4 for my internet connection. (going off...

The IPv6 is enabled on my router thru my isp. But it still doesn't come up on my series x. I also cannot disable the IPv4 for others in the house is using it.

I'm Samy an independent advisor. Welcome to the Xbox community. How are you?

You will need to talk to your ISP to see if it is possible to disable the IPV4 protocol, it is possible that if you disable this protocol you will not be able to use other services with your connection.

The console works with IPV6 automatically if your network has this protocol. You will also need to speak with your ISP to see if they have or can enable this protocol on your network.

makes diddly squat difference.

As above, doesn't make much difference...only time to be worried about it is if you are having connection issues with your game. I use IPV4 as my ISP doesn't offer IPV6 and I have zero connection issues on my Series X on Wi-Fi....well, aside from issues caused by games themselves of course.....<angrily looking at you Forza Horizon 5!!!>

Teredo isnt actually a program or file. It has to do with tunneling an IPv6 connection on a IPv4 internet connection. You might check with your ISP and see if they offer IPv6 in your area. If they dont xbox live seems to have an issue with tunneling. I
would recommend going into your router and see if your router is tunneling IPv6 to IPv4 and just disable the IPv6 and just use IPv4. Xbox seems to run great off a true IPv6 connection but doesnt do well if you are tunneling it from the older IPv4.
