Sorry for the late followup.
My reading of the strip was that the each colony of nanobots had to
exist in a single /64 subnet. They would naturally use RPL and probably
6lowpan to communicate. I don't think that having consumed a part of
the earth that the nanobot dies, it just becomes part of the routing
layer.
