This is pretty terrifying. Like IPv6 is good and all but what do you think all of those sensors are doing? Spying on citizens. It's super weird that anyone would want to be associated with that.

Not sure why downvotes - very valid point for China.

Do they really have a choice?

> designing for the deployment of 198,000 sensors per square kilometre

I wonder if they can sense my unease at that level of surveillance

> supporting over 1 million Internet of Things (IoT) devices per square kilometre

A black hat hackers wet dream. In just one square kilometer, you can have a 1M+ botnet.

That assumes they have general connectivity.

I help run a bunch of gear in a data centre, and all of our IoT stuff (PDUs, cooling) don't have gateways to the public Internet. They're on a segmented VLAN/subnet which you have to contact through a jump box: no routing anywhere else.

But can they access Github.com?

The Great Firewall possibly notwithstanding, yes:

> The office network at Xiong’an NGN Lab, a test case from the wider city, includes export routers, core switches, and network interconnection systems (NAT64+ALG), all deployed in a dual-stack environment. Office computers and OA servers operate in an IPv6-only area and communicate with external IPv4 network nodes through network protocol translation equipment and the interconnection system.
