% A micro allocation in V6 is quite a bit different to V4 in that the basic /64
% unit should cater for virtually unlimited numbers of hosts. Allowing a small
% number of bits for subnetting & routing would be all that's needed, so I would
% suggest anything between /48 & /64 would be more than adequate.

Er, that is pretty much exactly the point I was trying to make.
If Brian is right and that group is successful in restricting
announcements to /29's, how much space is wasted for the sixty
nodes that form the cluster "www.bigco.com" that has connections
to 20 major ISPs?
