Depending on how much you self host, you may find it hard to keep track of your devices’ host names. So what are your naming conventions to keep track everything? Some people stick to descriptive names, others pick themes, like Greek mythology.
Personally, I use Japanese emperors. I’ve made it all the way to Seinei. Luckily I still have some breathing room to add more services and servers. Much to my wife’s chagrin. :)
My network mostly uses NPC and summon names from Final Fantasy XI, because I played that game for many, many years and can associate the personalities of those characters with specific roles the host needs to have. I’ve also considered using Pokemon names for similar reasons, and with over 1000 current Pokemon species it’d be hard to max out in a home environment.
