You mean like /56 and (much worse) HD-ratio 0.94? :)
Well, I remain to convinced that a typical end-user household can find uses for more than a 100 different *networks* - but then, it's by no means mandatory to assign /56s, as the policy explicitely allows assignments of /48 (which we discussed last year in Rome to make it very clear how that is currently counted regarding usage ratio). I can't actually say for which classes of networks a HD-Ratio of 0.94 will work, and for which classes it might fail. It does give the ISP quite some slack (for example, a /32 is considered "full" if an efficiency of 37% is reached - as opposed to the 80% in IPv4 today [RIPE-512, Appendix A]). If that is not sufficient or does not really "fit" real-world networks, maybe we need a different HD-Ratio, or a different "fullnesss" metric altogether - your suggestions are welcome.
