[Question] What is the purpose of "NoT Wired" and "NoT Wifi" compared to "IoT Wired" and "IoT Wifi"?

Kia ora, Dimitri 👋

Many thanks for taking the time to document your use of Home Assistant. I'm sure I'll be using your work to use ideas... 👍

I have a question about your use of "NoT Wired" and "NoT Wifi" as subnets in your network, compared to "IoT Wired" and "IoT Wifi". Is this simply so that you can have "smart devices" in your network that are not able to access "the internet"? That is, they are isolated solely within your local network?

Many thanks, Jon
