My only currently active machine is a laptop named buttwarmer as per my cat's suggestion.

Ubiquitous and Tiamat are my servers, Polyglotal for my home assistant voice endpoint, and some more. Points for the reference

I wouldn't say my hostnames are very creative, but they all have some kind of backstory.

Main desktop: POwOful
It's a pretty powerful desktop, so why not call it that :)

Laptop: LenOwO
Can you guess the laptop brand?

Server 1: Shitbox
It's my first server box I ever built, so it's underpowered and pretty shitty.

Server 2: Stowage
My proper server with actual data parity, and it's pretty powerful

Server 3: Jank
This one is another shitmix of hardware with random harddrives in raid 0. I am aware that they'll die at some point, and all of that data stored on it will be lost, so i use it as temporary storage whenever I need to copy something from one machine to another.

Robot vacuum: suckywucky
Yea....

My media server is called "The_Nexus."

My phone when I host anything on it is "The Hackinator 9000" because I think it would be funny for a normie to see and freak out.

I do marvel weapons/artifacts:

Phone: Mjolnir

Tablet: Stormbreaker

Laptop: Darkhold

Earbuds: I.C.E.R

Backup NAS: EyeOfAgamotto

Etc, etc 😅

I went with alpha, beta, gamma ...

Desktop: Octiron
Laptop: Octogen
Phone: Octarine

@Krik For my personal devices, i use the names of the 12 Colonies of Kobol from Battlestar Galactica. So I currently have 2 laptops: Aerilon and Caprica. When I get a new phone, I'll probably name it Scorpia or Tauron.

Choosing a good naming scheme depends on how many you need, and how often you add to your collection.

I mostly use battlestar galactica ship names for my own hardware, but it's been mixed with boring '.mydomain.foo' names as well. I should rename a bunch of stuff around and include them in my DNS.

Charybdis, hippo, appa, Momo, pabu

Current homelab+desktop+laptop host count here is 22. All anime characters or references. It’s a fairly large pool to pull from, so it’s worked for me for 20+ years now. Mobile devices (phones, tablets, etc) and game consoles aren’t really as clever though.

All of them are in a piHole DNS though so no host files keeps it easy to track. Services have names that mostly are just what they are though and cnames to the matching host that hosts them (or load balancer, whatever)

I select hostnames drawn from the ordinal numerals of whatever language I happen to be trying to learn. Recently, it was Japanese so the first host was named "ichiro", the second as "jiro", the third as "saburo".

Those are the romanized spellings of the original kanji characters: 一郎, 二郎, and 三郎. These aren't the ordinal numbers per-se (eg first, second, third) but are an old way of assigning given names to male children. They literally mean "first son", "second son", "third son".

Previously, I did French ordinal numbers, and the benefit of naming this way is that I can enumerate a countably infinite number of hosts lol
