How do you organize your DHCP clients? - eviltoast

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.

    How small a client list are we talking? If it’s that small, then that would beg the question, why would you need dedicated ranges in the first place?

      A couple dozen devices maybe. I don’t really need dedicated ranges, but it’s nice to know exactly which device I’m looking at just by the IP when reading logs.

        I’m not saying in anyway that what you’re doing is in anyway wrong. It’s good that you’re thinking the way you are. Just saying, if you’re in this frame of mind now, it’s a good time to look at vlans. Think dedicated ranges with the benefit of reduced traffic saturation.

        Checking logs is perhaps the only real reason I can see for reserved ip-s. But then again you can do reverse lookups - and like I said in another reply ipv6 is dynamic by nature, so any device will only stay on the same ip for the configured amount of time.
        You might not know, but several of your devices might already be communicating using ipv6 on your home network. Both windows and iOS will use link (osi layer 2) local IPv6 and mdns for discovery and communication. This is not true if your switch denies IPv6 but you’d need a level 2 switch or some way to block IPv6 multicast for that.
