One of the key things with IPv6 (IMHO) is to stop thinking about addresses,
and instead just think about networks. Judging by Owen's earlier mail I
may not have that quite right and the key might even be to think about
hierarchies - in either case counting the number of individual addresses is
something we just don't need to do any more.
