En otras palabras y utilizando la siguiente analog\u00eda la direcci\u00f3n IP es como el nombre de la calle y el n\u00famero de casa de una persona.<\/p>\n<p>Una direcci\u00f3n IP es una direcci\u00f3n l\u00f3gica que puede cambiar constantemente y que se asocia a la tarjeta de interfaz de red (NIC), no confundir con la direcci\u00f3n MAC que es una direcci\u00f3n de hardware, adem\u00e1s, otros conceptos b\u00e1sicos asociados a la direcci\u00f3n IP que debemos tener en cuenta son la m\u00e1scara de subred y la puerta de enlace predeterminada (tambi\u00e9n llamada pasarela o gateway) .<\/p>\n<p>Actualmente hay dos tipos de direccionamiento IP, IPv4 (Internet Protocol version 4) e IPv6 (Internet Protocol version 6), cada uno con su propio formato. IPv4 utiliza el sistema binario para representar las direcciones IP mientras que IPv6 utiliza el sistema hexadecimal.<\/p>\n<p>IPv6 es el direccionamiento que reemplazar\u00e1 a IPv4, debido al crecimiento constante de dispositivos de red en todo el mundo, actualmente el n\u00famero total del direcciones IPv4 ya no son suficinetes para satisfacer dicha demanda, por tal motivo IPv6 ya est\u00e1 en producci\u00f3n permitiendo tener un n\u00famero mayor de direcciones IP debido a su sistema num\u00e9rico de base 16 (Hex).<\/p>\n<p>En las siguientes publicaciones trataremos a detalle cada uno de los esquemas de direccionamiento.<\/p>","protected":false},"excerpt":{"rendered":"<p>IP addressing is one of the most challenging and essential topics in TCP\/IP.
