To this day, my favorite naming scheme I ever encountered was names of elements, everything CNAMEd to the elemental abbreviation, with the last octet of the IP address as the atomic number. It was for a geophysics group, which probably made it a little more discoverable/easily spellable.

That might work for a private network, but what if you have a /24 and need to use the entire range?

Maybe find molecules with the corresponding molar mass, e.g. glucose = C6H12O6 = 180?

I had that idea ages ago and I'm glad someone actually used it.
