I don't want to make the same mistakes as IPv4. That is why I
want to give an IPv6 /32 to every IPv4 LIR. With IPv4 we made 
a mistake by trying to be too careful with class C address blocks
and again with small CIDR blocks. Instead of giving out large
blocks of class C space, we created the swamp. When CIDR
came along we continued to give out blocks for one year or
less of growth and we bloated the global routing table.

With IPv6 we do not have to worry about waste. Every LIR
gets a /32 from a reserved /29. When addresses are issued to
customers, everybody gets a /48 except in special circumstances
where a /64 or a /128 would be assigned. I don't think there will
be very many special situation that justify a /64 assignment today.

This means that we have a very simple straightforward system
that allows LIRs to grow 8 times before we even begin to create
anything that is similar to past history.

The key to avoiding the mistakes of history is to forget about
conserving address space. It is not a scarce resource; we have
lots of it.
