[ppml] tossed over the wall...

Thomas,

I have to admit some confusion.  It took quite a bit of effort to rid  
the routing systems of fixed network boundaries in IPv4 (and, in  
fact, there are still vestiges here and there).  Is there some reason  
that IPv6 makes dealing with variable length network masks more  
complicated than IPv4?

Thanks,
-drc
