Likewise, not all broadcast adresses necessarily end with .255, so filtering .255 won't help anyway in the presence of something like a /25 with a X.X.X.127 broadcast.Agreed but it is not easy for a hacker to determine CIDR masks. It is my impression that the only thing being sent is classfull broadcasts.
Further, smaller networks (which, theoretically speaking at least, have fewer hosts) would be less useful in a smurf attack than larger ones, as there would be less of a multiplying effect.
