[iot-wg] New on RIPE Labs: Visualisations of Periodic IoT Traffic

Hi Poonam

Thanks.  The concern here is that the device could choose to identify as
something else through a set of false communications.  It is indeed an
interesting area of research.  I am not saying there is nothing to be
done, but it is something that requires careful consideration as we aim
toward automating policy.  I fear in particular that the cloud makes
this quite a bit harder, and IOT manufacturer use of their own DNS
infrastructure will make it yet more difficult, because we are all using
the same cloud infra.
