+ | [[Megan]] and [[Ponytail]] are in orbit while evil nanobots are devouring the earth in a swarm. The nanobots stop after devouring 40% of the planet. This is a take on the "gray goo" scenario in which self-replicating nanobots destroy the earth while creating more and more of themselves non-stop. | ||
− | + | However, the nanobots are only able to destroy 40% of the planet because 40% of the earth mass = (# of {{w|IPv6}} addresses) x (A few cubic microns). Without more IP addresses, the nanobots cannot continue to replicate (assuming that each nanobot must be individually addressable). IPv6 supports approximately 3.4×10<sup>38</sup> addresses while the mass of the earth is around 5.97×10<sup>24</sup> kg or 5.97×10<sup>36</sup> ng (nanograms). The number of atoms on earth are somewhere at 1x10<sup>50</sup>. [[Randall]]'s guess on 40% of the planet doesn't match any of these values. | |

This is a joke on the shortage of IPv4 addresses. The only difference is that we are on {{w|IPv4}} and the nanobots are on {{w|IPv6}}. | This is a joke on the shortage of IPv4 addresses. The only difference is that we are on {{w|IPv4}} and the nanobots are on {{w|IPv6}}. | ||
