IPv6

How can I change my protocol from IPv6 to something else?

Why? The only other protocol is IPv4. Most networks will work with both.

problem with VPN when using this protocol.

If you are on a home computer, you can disable IPv6 on it. Depending on the VPN service you are using, if it uses a virtual network adaptor, you may be able to disable IPv6 on just that.

Try Googling for something like: "Disable IPv6 on Windows 10" or whatever operating system you are using.
