I do believe I'll let dns answer this for me
$ host -t a -l universe

I guess that explains why it is that I use dns for this rather than just a simple /etc/hosts.
For the explaining of what most of the systems are, I also have text records:
$ host -t txt -l universe
centauri.universe. TXT "DEC Multia"
ceres.universe. TXT "Personal DecStation 5000/20"
charon.universe. TXT "VaxStation 4000/VLC"

It's a little excessive, isn't it? Now, if only I had enough power points to power them all up at once.
