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.
I use it for enterprise scale infrastructure deployments. But for a home network, it seems like unnecessary work.
I reserve everything below .100 for static IP devices like switches/access points and my work devices, the rest is all dynamic lease DHCP.
I could just set up a dashboard or figure out how to use hostnames, but I’m a caveman and I remember the IPs of the devices I want to ssh or browse to in my network.
I don’t see the need, everything gets IDed by its hostname.
The only thing with static DHCP is IoT stuff that needs a consistent IP for HA to connect to it, and servers.
I live alone. So I just have reserved IPs for each of my devices. Any new device gets assigned >200 so that I can easily identify new stuff, or rogue devices - which hasn’t happened lol. The only special IP is my pihole that gets 192.168.1.2 next to my router since I consider it infrastructure basically. Plus pihole is my dhcp server and dns obviously
I like the range for new devices- hadn’t thought of that!
Yeah makes it easier to identify new stuff. Like I recently added a new NAS into my network, and I didn’t have to try and figure out which device it was identified as. Just sitting at 200.1 so I could give it a name and assign a static IP.
I don’t.
I currently use 192.168.6.0/24, set DHCP to 100-199, and statically assign a few servers outside that range. Anything else can use DNS via DHCP because I use Windows for AD/DNS/DHCP.
Sounds like fun but watch out for man in middle…home tech support!
Remember upper executive mgmt (wife) will have priority demands and expect to bypass all support/ticketing processes c/o direct access/shoulder tap, 24x7.
Tip - create high priority user stories for your upper exec mgmt needs and your rest activities (sports, call of duty, tinkering in garage/shop/man cave, etc etc etc et al) so your impl supports your key stakeholders while also aligning with your favorite best practices.
.local is the important part imo—actually, tbh I am not a super fan of the .local dns method and how it punks networks (basically like entering a crowded bar and yelling YO BRAH!) BUT it is simple and low effort (see high pri user stories).
Good luck with your PI plan, could you include us in PI retrospective so we can learn from you? Godspeed.
:]
I have a few vlan subnets, one for IOT devices (smart junk, automation, media players etc), one for general LAN devices (mostly computers, NAS etc), one for VMs and other services and one for guest access. all with their own fairly simple firewall rules to eachother and to the web. there are also matching Wifi networks for IOT, Main and Guest that are on those Vlans.
As for DHCP, I tend to set the DHCP ranges for xxx.100 - xxx.254 and anything below 100 is for static allocations. all in standard 192.168.x.x ranges, no need to go bigger than that. I only have IPv6 for the VMs for testing cause i’m still learning how to use that properly and safely.
I put them into groups, servers, consoles, computers, phones, smart devices, media. Between 10 to 20 per range.
Everything else the dhcp server gives out ip over x.x.x.150 so easy to see new stuff.
