So you have a unique local prefix, for what exactly?
Since you will come up with something totally different after a power
outage, when you need extra hassles least, you cannot use it to
identify a fileserver, appserver, etc; basically, you can not -use-
these addresses for anything that is not based on dynamic polling.
