Hace un poco más de 20 años atrás, estaba todavia en el colegio <br>
secundario, y habia empezado a leer RFCs de IETF -- con algo de <br>
frustración al ver que no habían RFCs con autores de la región.<br>
<br>
Pasó mucho tiempo (y muchas cosas) desde ahí... desde empezar a escribir <br>
un primer internet-draft, a pedir dinero prestado para poder asistir a <br>
mi primera reunión, renunciar a trabajos para poder hacer ingenieria de <br>
Internet (con un futuro verdaderamente incierto :-) ), y otras tantas <br>
cosas más.<br>
<br>
Los tiempos luego cambiaron, pero algunas cosas no: las reglas y los <br>
obstacúlos para participar en IETF jamas fueron los mismos para quienes <br>
veniamos del c* del mundo -- o, mejor dicho, para quienes no <br>
pertenecemos a la comunidad dominante de IETF (ver <br>

En todo este tiempo, Diego Maradona fue un motivador imprescindible... <br>

Subject: Fwd: RFC 8981 on Temporary Address Extensions for Stateless <br>
Address Autoconfiguration in IPv6<br>

Folks,<br>
<br>
RFC 8981, entitled "Temporary Address Extensions for Stateless Address <br>
Autoconfiguration in IPv6", has finally been published: <br>
<a href="https://www.rfc-editor.org/info/rfc8981" rel="noreferrer" target="_blank">https://www.rfc-editor.org/info/rfc8981</a><br>
<br>
It has been the product of over four years of work.<br>
<br>
It is revision of RFC4941 -- the so called "IPv6 temporary addresses", <br>
also known as "IPv6 Privacy Addresses".<br>
<br>
This revision does a number of interesting things, including:<br>
<br>
* It employs a different algorithms for generating the Interface <br>
Identifiers (IIDs)<br>
<br>
* Addresses issues present in RFC4941, such as re-using the same <br>
interface identifier across different prefixes<br>
<br>
* The lifetimes of temporary addresses are reduced, thus reducing the <br>
average number of addresses that may be in use at any given time.<br>
<br>
* The lifetime of addresses is randomized, such that it's harder to <br>
infer when addresses are re-generated.<br>
<br>
Thanks,<br>

<br>
This document describes an extension to IPv6 Stateless Address<br>
Autoconfiguration that causes hosts to generate temporary addresses<br>
with randomized interface identifiers for each prefix advertised with<br>
autoconfiguration enabled. Changing addresses over time limits the<br>
window of time during which eavesdroppers and other information<br>
collectors may trivially perform address-based network-activity<br>
correlation when the same address is employed for multiple<br>
transactions by the same host. Additionally, it reduces the window of<br>
exposure of a host as being accessible via an address that becomes<br>
revealed as a result of active communication. This document obsoletes<br>
RFC 4941.<br>
<br>
This document is a product of the IPv6 Maintenance Working Group of the <br>
