I have a small ISP customer who is not multi-homed, and is using about
a /21 and a half of space, and is expanding. Their upstream is
refusing to give them more space, so they wanted to get their own, and
give back the space to the upstream, with the possible exception of a
small block for their servers, which would be very difficult to
renumber. We explained this all, and the response we got from ARIN was
that we needed to have a full /20 from the upstream, at which time we
could easily get a /20 of new space. In order to qualify for the
immediate need, we would need to show need for the entire /20, of
which we would need to fully utilize (renumber into) within 30 days.
That is not even remotely possible.

And worse, it violates best practices[1] rather thoroughly.

Cheers,

[1]Never expand to anything smaller than twice what you have now.
