zeroconfig IPv6 tunnel
The use of NAT devices all over the Internet has made peer-to-peer exchanges unreliable. The rise of IPv6 should repair this, but it will still not be reliable until all peers have implemented IPv6. Such IPv6 implementation could be arranged on the fly with a tunnel mechanism that does not rely on router co-operation or manual configuration. This specification details such a method of embedding IPv6 into UDP and IPv4. It employs embedded Router Solicitation to configure the tunnel's public IPv6 address, and Neighbor Discovery to try to find the remote peer over more efficient IPv4 routes.
