> Empezamos el a?o con una noticia de RIPE. Recientemente se present? una pol?tica que puede ser ?til para nuestra regi?n. Proponen utilizar HD-ratio (http://www.ietf.org/rfc/rfc3194.txt) para las asignaciones adicionales en IPv4. Hasta ahora ten?an una pol?tica como la nuestra donde ped?an el 80% de uso en los bloques asignados para que la entidad pudiera pedir otro bloque al registro.
>
> El problema de utilizar un % en lugar de HD-ratio es que no existe un valor que sea apropiado para todos los tama?os de proveedor. Si utilizamos % bajos puede haber mala utilizaci?n, si utilizamos % grandes ser? imposible para los proveedores con redes complejas lograr esa eficiencia.
>
> Una explicaci?n simplificada del HD-ratio seria: en lugar de contar el % de IPs utilizados contamos el % de utilizaci?n de los "bits" asignados. Es decir, si me dieron 10 bits (un /22) y me piden un HD ratio del 90% (0.9) entonces tengo que tener usados 9 bits (un /23) antes de pedir el siguiente bloque.

> La pol?tica de RIPE pide un HD-ratio del 95% (HD-ratio=0.95) y pueden encontrarla en: http://www.ripe.net/ripe/policies/proposals/2005-1.html. En esa misma p?gina con el t?tulo de Rationale: ver?n la justificaci?n y mas abajo unas tablas donde pueden ver la aplicaci?n del HD-ratio a diferentes tama?os de bloque.
