Now that's confusing.. doesn't CIDR supposedly make it so that one IP is no better or worse then another? Why do people base their filtering policies on where things are in the "Classful" space? How is 64/8 any different then 216/8.. they allocate out of both of them, it's a crapshoot what you get since ARIN denys responsibility to provide routable IP space, yet there is space that is "more" routable than other space.
you may want to look at the rirs' web pages where they report what prefix sizes have been allocated out of which /8s. that is what some folk use for prefix filtering policies. randy
