Redes

Se deben identificar 3 cosas
– Bits de Red
Corresponden a la mascara por defecto
– Bits de Sub Red
– Bits de Host

VLSM: Máscara de Subred de longitud variable
– Consiste e n asignar la máscara de red de acuerdo a la cantidad de host.
– Lo importante es no desperdiciar IP’s.

Sistema antiguo criterio es ver la red mas grande.

VLSM PASOS
– Ordenar redes de la mas grande a la mas chica
– Definir cuantos bits necesita cada red y cual
es la mascara que mas acomoda
