Its really not that hard. Sadly, my ISP doesn’t offer IPv6 yet, but for my vServer, enabling IPv6 was just a checkbox during creation. Then, you need to make sure that the service (e.g. webserver) also listens on the IPv6 address and maybe tweak the configuration of the webserver to actually serve websites via IPv6. Also, check your firewall settings. Lastly, you need to set the DNS AAAA records and you’re done.
You’re right, that’s an option. I could set this up at my router, this way it would be almost indistinguishable from IPv6 via my ISP.
