Necesitaremos comprender el uso de la máscara de red y su aplicación sobre las direcciones para extender las posibilidades del formato Ipv4 y trabajaremos con ella para enrutar nuestras redes en el futuro y ampliar los rangos de red o de host según las necesidades que tengamos en un momento determinado.
Ayudados por las operaciones lógicas, el sistema binario de las direcciones ipv4 y las posibilidades del formato de la máscara nos introducirnos en las posibilidades del subnetting y supernetting, ampliaremos conocimientos que nos permitirán trabajar cómodamente con los rangos y usar la máscara de red para ajustar los disponibles dividiendo o multiplicando una zona u otra.
También repasaremos los rangos de redes públicas que son asignadas en internet viendo sus límites y entendiendo las clases que surgieron en los primeros sistemas de networking.
Saludos.
