disabling ipv6

Hi Razql cC, 

IPv6 is most often controlled by your router and not on your Xbox, but you can manually set your DNS and IP on your Xbox to point to your router. 

IPv6 is a bit better than IPv4 in the sense that it doesn't use NAT. But has been known to cause problems on the Xbox One. 

I suggest you check your router settings to disable it. Depending on the router you have, you should be able to turn it off in the Advanced Settings listed as IPv6

You can't (and shouldn't) disable IPv6 on the Xbox One. 

The Xbox One mainly uses IPv6 to transfer it's multiplayer data, however, if IPv6 is not natively available, it'll use Teredo to tunnel IPv6 through IPv4. 

So even if you only have IPv4 in your network, the console will still use IPv6. 

Is there a specific reason why you wish to disable IPv6? Since IPv6 is actually better for multiplayer gaming, you would want to have it enabled.

Could you elaborate on your reasoning? IPv6 is far superior to IPv4 at this point, and even the issues which were occurring on Xbox One when IPv6 first began to be available now appear to be worked out. If IPv6 appears to be causing issues, it is entirely possible that it's an issue on your ISP's side. When mine first started making IPv6 available through their DOCSIS 3.0 and 3.1 gateways, there was some difficulty with the router not being sure which one to assign to a given device. I often ran into a "strict" or "moderate" NAT even though I was showing an IPv6 address, because the router was also assigning an IPv4 address, and that was resulting in the NAT conflict. I could forward the ports for the IPv4, but it was still an off-and-on issue. Since my ISP has resolved those issues and fully switched over to IPv6 for all compatible devices, I haven't had a NAT issue or any other multiplayer problems for 2 years now.
