you get the idea, in my network I don’t add the underscore but I figured for explanation sakes I would here. I’m sure without explaining what each server is, whether it’s a VM from proxmox or an actual machine, you know what they are when they show up on your router. I added the sequence numbering for future proofing my self hosted setup in case I get another machine in the future.
I name my personal devices after Nasa projects and launches and my wife, well her phone is just called iPhone 1, 2, 3 etc. so everything is easy to spot on my home network.
