This address is mainly used in the case a device -that-is-not-behind-a-CPE-
wants to initiate the tunnel. In this mode of operation, dual-stack lite is
a very simple alternative to NAT-PT.

Now, I suggested 0.0.0.1, but this may not be the best choice. I will
probably end up asking IANA to reserve an address for this.
