D-Link: Switching to IPv6

Could you describe in more detail what it is that you need help with, in terms of IPv6

IPv4 / IPv6 is all up to your ISP if they support IPv6 and so does your router / modem then you will definitely get IPv6. You may need to login to your router as a administrator and change it but you will need to contact your ISP because there is a login
screen you need to pass before getting in. But not all ISP's have a login screen it's just there for security.

IPv6 and Xbox support

IPv6 on Xbox One

Xbox One can connect to networks using two protocols that allow devices to transmit information: the traditional IPv4 communications protocol, and its newer version, IPv6. For Xbox One to connect to the internet using IPv6, your home router needs to have
IPv6 enabled, and your internet service provider (ISP) must support IPv6.

What’s IPv6?

Internet Protocol version 6 is the most current network protocol, bringing several improvements over IPv4. Most important, IPv6 expands the number of possible IP addresses (the unique numbers that represent every device on the internet). And—most useful
for Xbox—the expansion removes the need for
Network Address Translation (NAT), which can interfere with multiplayer gaming and chat over IPv4 networks.

What if my Xbox One isn’t connected using IPv6?

Your Xbox will work normally without IPv6 connectivity. However, for the best possible experience, we recommend enabling IPv6 on your network. Several Xbox One features already make use of IPv6, and we’re building more.

How can I tell if my Xbox is connected using IPv6?

Here’s how to check:

1. On your controller, Press the Xbox button
   to open the guide.
2. Select System > Settings > Network.
   
3. Select Network settings.

If your Xbox One has IPv6 connectivity, your Current Network Status will read
IPv4 & IPv6. (To see your actual IP and gateway addresses, select
Advanced settings.)

My Xbox is using only IPv4. What should I do to add IPv6?

Several home routers support IPv6 but disable it by default. Check the manual for your router, or visit our
Networking Hardware Information support forum.

My router has IPv6 enabled, but my Xbox is connected on IPv4. What else can I do?

Try contacting your ISP to see if IPv6 is available in your area.

You can only switch to ipv6 only if your internet provider supports ipv6.
