The host is behind NAT and uses Teredo to get globally routable.
How to make it easily-reachable? For IPv4 case we just use no-ip or dyndns, however for ipv6 I don't see AAAA replies from dyndns's nameserver even though I specified "IPv6 Address (optional)":
$ dig vi.dyndns.org @ns1.dyndns.org | grep -v '^;' vi.dyndns.org. 60 IN A 220.127.116.11 ... ns1.dyndns.org. 60 IN A 18.104.22.168 ns1.dyndns.org. 60 IN AAAA 2600:2001::75 ... (I was expecting to get): vi.dyndns.org. 60 IN A 22.214.171.124 vi.dyndns.org. 60 IN AAAA 2001:0:53aa:64c:c5b:4f1e:a9c6:61b1 ...
How to make my host known in IPv6 world? Are there services like dyndns or no-ip, but for ipv6?
