With our providers, when we request new addresses we have to be able to
justify them. By that I mean they want to see that we will actually be
using 80% of the assigned addresses within three months. In the case of a
company wanting to multihome some web servers, chances are that they're
really only going to use a handfull of addresses.
So (and I admit I've had to do this myself--twice) you have to fib when you
apply for the addresses. If you were to say that you only intended to
use 10 addresses but you really need an entire /24, they might not approve
it. Our current provider, Sprint, would *not* approve a /24 assignment on
my first request when I stated our actual usage expectations. Miraculously,
by the time of our second request our usage expectations had risen
enormously. :-)

cannot
