As I asked before - I'm really keen to actually do this stuff - but all
I get is people who haven't done it telling me theory and not how it
works in practise in a real ISP of some scale.
Telling customers "well, you might get renumbered randomly" isn't going
to work, no matter what the theory about it all is. They do crazy and
unexpected things and bleat about it even if you told them not to. At
worse they stop paying you and leave!
My hope is that PD will be used for the majority and statics will be
small in number. My FEAR is that customers have already been
conditioned that v6 will mean statics for everyone because v6 has so
many! (This has already been the assumption many have made from the
