Do you give names to your computers? Do you stick to some rules?
I love The Expanse, so...
Home network domain = Sol
Home server = Belt, and its VMs and LXCs are dwarf planets/asteroids, so Eros, Ceres, Vesta, etc.
Network devices are planets: switches (Earth, Mars) and APs (Venus, Jupiter)
Personal PCs are belter ships/stations: Tycho, Medina, Tynan
Work is MCRN: Donnager
Phone is Razorback, printer is DeWalt
...and Rocinante? *BSD test laptop
