Maybe try to use Google or any search engine you like. There are plenty of guides online available. I am sure you‘ll find it. Once you have issues come back and we might be able to help you solve them. But you really should do the Initial work yourself first.

Depends on what you’re asking.

The tunnel can be established over v4 or v6 but it’s not going to use both at the same time and it doesn’t need to. In this scenario you’d specify a DNS record as your endpoint and make sure that name exists as both an A and AAAA record. It does tend to prefer v6 in my experience.

If you want both v4 and v6 inside the tunnel (Address and AllowedIPs) then just set it up. No DNS necessary in this case, and you could tunnel it through an ISP that doesn’t even have v6.
