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.
