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?
All of my machine names are related to Elvis Presley. Elvis has been my desktop PC for years, and I have or have had Priscilla, Lisa-Marie, ColonelParker, Blue-Hawaii, Hound Dog, Memphis, Tupelo, and Graceland. I want to rethink this a bit to have to flow better, maybe have Graceland as my network name, or maybe the router. Also thinking about changing to something space-related or Norse Mythology as the theme.
