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.
It’s called CIDR notation, the number represents how many bits of the whole address represent the “network” part of the address. /8 is equivalent to a subnet mask of 255.0.0.0
