How to switch ip4

IPv6 settings are found in your modem/gateway settings, which you must most likely configure from your web browser. Accessing those settings depends on the model; you'll need to consult any documentation to find the web address and default login (if not
configured yet).

If your modem/gateway was issued by your ISP, consider giving them a call and ask:

1. Does their service support IPv6 addressing?
2. If so, has the hardware they issued you able to support IPv6?
3. If so, how do you configure it?

Yes i have both an IP4 and an IP6 address

Well if you are talking about ip6 then no as that came.out.way after

Most likely ypur router supports ip4 already just hand out.ip4 addresses

How do I change the protocol in my Xbox from IP4 to IP6

This is a function your ISP would have to enable, and its not so much of "change" but an addition to the addressing protocols the network uses.

Contact your ISP to determine if they allow IPv6 and ask them to enable it.

I did solve my problem. To recap, my ISP does support IPv6, my router also supports IPv6, the various computers on my home network are connected via IPv6, but my Xbox was reporting only IP4 connection. While I had turned my Xbox off, I didn't do a hard
reset so the Xbox, despite being "off" it was still assigned its IP4 address. I unplugged the Xbox, and for good measure I also unplugged the Cable modem and router I used. Left them off for about 5 minutes. Restarted the cable modem and router till they
fully came online so the DHCP on the router was functioning. I then plugged the Xbox back in which forced a reassignment of its network address and viola, I had both IP4 and IPv6 addresses for the Xbox. In the end it was the fast start-up mode of the Xbox
that was foiling me. Hopefully that helps you as well.
