HI Taru, Interesting article. I have been to many conferences where the IoT has been touted, and seen some excellent examples of its use in the "wild" I am wondering though if you would be able to address some issues I am thinking about in the security domain. a)don't need NAT for IPv6 we will have direct addressing of our IoT devices ie they will be in some cases directly connected to the internet. b) there are also numerous sites that publish default passwords of IoT devices. c) there are a large no of IPv6 addresses making spoofing so much easier.
