I definitely agree about not having magic, built in ranges. If I were to more fully implement this, I'd likely separate out MulticastIPs from AllowedIPs so that users do not unwittingly turn an intended-unicast subnet into an accidentally-multicast subnet. It would all, of course, be opt-in only. ~Derrick
