Yes and no.
First, assuming you are limited to a /32 is absurd. I=92ve personally =
helped multiple organizations obtain various size allocations ranging =
from /32 to /24 with little or no difficulty so long as the size of the =
network warranted it. (The biggest challenge was a large organization =
that I had to work at showing ARIN was, in fact, an ISP and not merely =
an end-user. They got a /24. In fairness to ARIN, it took me a while to =
realize myself that they were an ISP before I approached ARIN. It was an =
odd situation.)
/48 for all customer sites is not at all unreasonable and is fully =
supported by ARIN policy.
Where Bill is correct is that some customers may have more than one =
site. The official policy definition of a site is a single building or =
structure, or, in the case of a multi-tenant building or structure, a =
single tenant within that building. Yes, this could technically mean =
that a college dorm contains thousands of sites and could justify =
thousands of /48s.
