"better aggregation" is actually harmful to efficiency. How do you get 80% usage out of something that is only 55% filled, but that you need to get aggregated into a single block? > Moving the HD-ration seems to me more useful in terms of managing the way > LIRs get their prefix, while changing the end-user prefix, is the easier > way, but the most hurting one in terms of facilitating the grow of home > networks (which in turn means innovation and more business for ISPs). Is anybody envisioning home networks with more than 100 subnets? What are people doing there? > Just look for the big allocations (/19, /20).

If so, then let's go directly to NAT with IPv6 :-( Please be somewhat more specific why a /56 would be a "severe restriction" to an end user. Vague handwaving doesn't help us find consensus here. > On the other hand, do we really believe is a problem to have a protocol that > might last for "only" 60-100 years?

People never assumed IPv4 would last for 30 years... so the chance that IPv6 will stick around for a VERY long time is quite large (if it happens at all).
