Perhaps because RFC 1812, "Requirements for IP Version 4 Routers" (which I believe is still current) needs to be updated/made obsolete? Excerpted from section 5.3.5: A router MAY have an option to disable receiving network-prefix- directed broadcasts on an interface and MUST have an option to disable forwarding network-prefix-directed broadcasts. These options MUST default to permit receiving and forwarding network-prefix- directed broadcasts. Or perhaps because the folks on this list haven't made it clear enough to their vendors that the default should be "off" <hint>. Kelly J.
