That's a very useful article.  I can't find in it (at a quick glance)  
anything that says whether the random address generation logic tries  
to generate the same (set of) random address(es) each time it is  
initialised.  That would be a useful property for keeping tabs on  
machines and would save the hassle of DDNS and the like.
