The point here is that breaking out the math based on the surface area of the earth is silly, as we do not utilize the surface of the earth in a flat manner...

What about network-based objects outside of our orbit? If we're talking
about IPv6 in the long-term, I think we have to assume we'll have
networked devices on the moon or at other locations in space.
