Comentarios
Una dirección de difusión identifica varios equipos. Los paquetes enviados a una dirección de difusión de difusión se envían a uno de los equipos identificados por la dirección. El direccionamiento de difusión es una característica IPv6 que se usa para actualizar las tablas de enrutador para un grupo de hosts.
