In other words, ip6 is not complete autogeneration. A part of it is fixed
in the same sense as a static ip4 space and the rest is autogenerated. That
fits very well into the notion of static IPs. In this case, we have to work
with a provider who issues us the fixed part of the IP6 addressing to us.
This provider is either our own ISP or someone who is willing to accept the
tunneled (over ip4) packets and route for us.
