I’m setting up DHCP reservations on my home network and came up with a simple schema to identify devices: .100 is for desktops, .200 for mobiles, .010 for my devices, .020 for my wife’s, and so on. Does anyone else use schemas like this? I’ve also got .local DNS names for each device, but having a consistent schema feels nice to be able to quickly identify devices by their IPs.
For work we have standards, ideally we separate VLANs by device type and firewall off their communication, but on a home network, I’d generally group by category. .1-9 network gear like switches and firewalls. .10-19 IOT. .20-29 servers & NAS. So on and so forth.
I’m paranoid so I have created a physically separate network for the IoT stuff. Everything gets its IP from the same server from a /25. The lower is the trusted network, high IPs are not. IoT network devices cannot open connections to the other network. A bit awkward, but works fine.
I see no reason to put iot devices on the same lan as my servers/home network, and I never suggest that to friends.
