Have you considered the possibility that you might be over-analyzing the joke here?

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.
