Note that it may be prudent to assign up your address space in
non-contiguous prefixes.

Consider the ramifications of assigning each client a /64 in a
sequential fashion, and then having to assign a particular client
additional prefixes at a later time.

If your network is not flat, then you just broke your ability to
aggregate your prefixes from the edge in.
