Sprint is the worst for pre-fix filtering for all but their own customers. I recently went through this with my old /24. It's still SWIP'd to MHSC but I can't use it.

Not many ISPs, smaller than /19, aregoing to be doingeffective ASN's either.I would take issue with the assertion that you need a /19 or larger to "be doing effective ASNs". My understanding is that as long as you get a block from former class C or "the swamp", you should be visible everywhere. We recently requested, and got a /21 from 65/8 from Sprint. A phone call and some pleading got them to change that to 208.8.16.0/21 AFAIK, that's reachable everywhere from AS19975 If that's *not* correct, I'd sure like to know...
