In your previous mail you wrote: Let me try to make most of my point somewhat more concisely: In programming, there are only three values: zero, one and many. What we need to do is come up with a good prefix size for networks that: - have no router => /64 for the connection link itself. - have one router => it depends on the number of links behind but it seems that /60 is right. - have multiple routers => if the topology is complex (HD ratio ~ 0.5) and the number of links ~ 10 then a /56 is right. IMHO the best is to authorize a /56 in all cases (i.e., move from /48 to /56 for common home networks) and leave DHCPv6 PD negociates the right value, "up to" /56.
