Configuring dense-mode in an ISP environment has proven to be suboptimal
in practice.  Hosts sending data to lots of multicast addresses creates
state throughout your network.  A few big operators were impacted pretty
heavily when Slammer first came out (I think later worms had some basic
intelligence in their network number generators to exclude 224/4).
