Yes, you'll be fine with a /20 from the blocks that ARIN allocates
from.
When we applied for IP space about a year ago, our /20 came out of 216/8.
ARIN is currently allocating from 64/8, 65/8, and 66/8, so providers
changed their filters to permit that. You can read various provider
filtering policies at http://www.nanog.org/filter.html ; Verio's is
the most restrictive.
Cheers,
Troy
