I get guest network. But IOT aren’t you just making it prone to be hacked and taken over as part of bot net or worse? Many IOT now are cameras, door bells etc etc. I would think privacy concern is a greater problem?
IoT is a VLAN on the DMZ network that only has the ability to see the Internet outbound and nothing else. No UPnP, no port forwarding, nuffin. There is no way to initiate an inbound connection, the IoT devices need to dial out.
