Mimicing a thread I saw elsewhere.
I generally use this list to name my machines: https://en.wikipedia.org/wiki/List_of_mythological_objects
For my main server I use loeding: a modified version of Lædingr, a chain forged by Thor to bind and were broken by Fenrir. (Norse Mythology)
No phantasy involved here.
Just my initials & “server” & a number.
Or, if the device isn’t exactly a server, it can also be my initials & “router” & a number, or “bridge” etc.
