You can get a Hurricane Electric free static v6 tunnel.

They have poor reputations and are blocked from streaming sites and so on. But when you're the server, that doesn't affect you.

Note that you need a static v4 and DMZ because the tunnel protocol is a very simple one - presumably because they run it on giant routers. It just puts a v4 header in front of the v6 header. No TCP or UDP.

I may be able to, but the millions of others won't. The solution needs to work out of the box for consumers.
