Another idea would be to give each non-/48 customer the
first /56 out of each /48. If you started out with a /30 or /31 RIR block , by
the time you run out of /48s, you can either start using up the
subsequent /56s out of the first /48, as it's likely that the first /56
customer out of the /48 would have needed the /48 by that time.
Alternatively you might have become more comfortable with giving each
customer a /48, and wouldn't require any of them to renumber - they'd
just have to shorten their prefix length.

Mark.
