I figured this should go here as well.

Is that an official recommendation? I currently have a single /56,
which I would like to distribute over several thousands customers,
each on a virtual server, with currently one static IPv4 address.
I can see how a /96 for each customer would be more than enough
(especially that since hundreds of customers are going to share
the same MAC, due to the low-overhead virtualization technology
used).
Presumably, in above context it would be a sane thing to parcel
the /56 into /64, each for one physical server's distinct NIC
MAC, and from each /64 a /96 for each virtual server?
