IPv6:
|

At the moment the iodined server only supports IPv4. The client can use
|

IPv4 or IPv6 nameservers to connect, and the relay nameservers will translate
|

between protocols automatically if needed. If the server hostname has an AAAA
|

record registered IPv6 mode will not work - in this case the client must be

configured with an IPv4 nameserver. The data inside the tunnel is IPv4 only.
