Are we really concerned about being smurfed by a /30, or even a /27? The essential problem is backbone class-C's, especially those in NAPs where coordination is nearly impossible. Smaller subnets tend to be in small ISPs' or customers' networks, which don't pose a threat since they lack the bandwidth for an effective attack.

This kind of filter won't block anything from their broadcast addresses, since they're not the .255 address.-- Stephen Sprunk "Oops."
