  # at least, things seem to be routed so that the vm can connect to this
  # IP even if it has nothing to do with vagrant or virtualbox. This may not
  # be an entirely safe assumption, but vagrant doesn't provide any kind of
  # better way to obtain a canonical reachable address as far as I can tell.
