I’ve ended up with a number of machines on my network, and a need to name them all in a somewhat logical way. For several years I had them named after the planets, which worked well until the PCs for myself, my girlfriend, servers and Raspberry Pi’s quickly summed up to more than the eight planets. I’ve broadened it somewhat to include any Greek/Roman mythological figure, but the system is definitely not as clean as it used to be.
Do you have a coordinated naming theme for your machines?
It doesn’t quite say that, but I think the meaning is essentially the same: “Don’t choose a name after a project unique to that machine.” - RFC 1178
For my homelab, I think that’s fine to do. I’m unlikely to have multiple Plex servers locally, for example, and if so, numerically naming them is fine - I provision with Ansible, and if I’m at the point where I’m having sequentially numbered hosts, they’ll be configured as cattle anyway. Also, having the names reflect the services a host provides makes it easier to match in my playbooks.
I think it’s a better scheme than turning to mythology, fiction, or animal species, which oddly enough RFC 1178 does encourage you to do.
