Laptops/desktopes: no real naming scheme, they use non-static DHCP leases anyway.
Physical servers: NATO phonetic alphabet. If I run out of letters something has gone terribly wrong right.
VMs: I don;t have many of these left, but they are named according to their function and then a digit in case I need more. e.g. docker1, k3s1. This does mean that I have some potential oddities like a k3s cluster with foxtrot, alpha, and k3s1 as members, but IMO that’s fine and lets me easily tell if something is physical or virtual. I am considering including the physical machine name in the VM name for new things as I no longer have things set up such that machines can migrate… though I haven’t made a new VM in some time.
Network equipment: Named according to location and function. e,g, rack-router, rack-10g, rack-back-1g, rack-ap, upstairs-10g, upstairs-ap. If something moves or is repurposed it is likely getting reconfigured so renaming at that point makes sense.
