Revision del draft que revisa la especificacion de direcciones 
temporales/de privacidad: 

Tiene impacto concreto:

* Reduce el numero total de direcciones de 7 a dos por prefijo.

* Cambia la vida maxima de 7 dias a dos dias.

* Arregla problemas de seguridad de las especificacion actual (RFC4941).

Personalmente implementé este draft para FreeBSD y Linux kernel. El 
codigo en cuestión ya es parte del arbol net-next.

P.S.: Para el interesado, aquí tienen un poco de background respecto de 
las mejoras recientes en materia de direccionamiento IPv6: 

Saludos, y que Maradona los bendiga,

Autoconfiguration in IPv6

    This document describes an extension that causes nodes to generate
    global scope addresses with randomized interface identifiers that
    change over time.  Changing global scope addresses over time limits
    the window of time during which eavesdroppers and other information
    collectors may trivially perform address-based network activity
    correlation when the same address is employed for multiple
    transactions by the same node.  Additionally, it reduces the window
    of exposure of a node via an address that becomes revealed as a
    result of active communication.  This document obsoletes RFC4941.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
