IPv6 support for VPN endpoints

[ffrediani]

Your service is very interesting and the information is very well clear and written on your FAQ. Well done for such level of detail and transparency !

Would you consider to add IPv6 support to all of your VPN endpoints (e.g: xx1.tunnelsats.com) ?
The providers you use (DigitalOcean, Vultr, Hetzner) all have native IPv6 support to their VPS offerings and it should be simply a question of making Wireguard listen on IPv6 socket and add the AAAA FQDN for each endpoint.

This should have not impact on clients with IPv4-only connection that will continue to resolve the A FQDN and enhance connectivity robustness by avoiding local CPE NAT a the home router and possibly at the ISP CGNAT. Even with the Wireguard connecting to a IPv6 endpoint it is still possible to pass IPv4 traffic inside de tunnel normally which fulfil the main propose of the service.

A lot of big Broadband Providers worldwide nowadays have full IPv6 support and therefore many people running Lightning nodes already have IPv6 connectivity to their nodes.
