On Windows it's not possible to bind to a multicast address but the OS will make sure to filter out all packets that arrive not for the multicast address the socket joined. On Linux and others it is necessary to bind to a multicast address to let the OS filter out all packets that are received on the same port but for different addresses than the multicast address And deprecate the multicast-group property and replace it with the address property. https://bugzilla.gnome.org/show_bug.cgi?id=707042
