Check the ARIN page, http://www.arin.net/initial-isp.html. Essentially, ARIN allocates a /21 or /20 of a "Reserved" /19. When our downstream got a /19 from ARIN, he announced the full /19 to defeat the Draconian Sprint 112 filters and copy-cats. Check with your downstream. They probably have a reserved /19 they can announce. And, of course, double-check with ARIN as this isn't my customer we're talking about. ;) >Mark D.
