Estimados/as,
FYI: https://www.rfc-editor.org/info/rfc8981
(mas abajo podrán encontrar un resumen técnico)
Hace un poco más de 20 años atrás, estaba todavia en el colegio
secundario, y habia empezado a leer RFCs de IETF -- con algo de
frustración al ver que no habían RFCs con autores de la región.
Pasó mucho tiempo (y muchas cosas) desde ahí... desde empezar a escribir
un primer internet-draft, a pedir dinero prestado para poder asistir a
mi primera reunión, renunciar a trabajos para poder hacer ingenieria de
Internet (con un futuro verdaderamente incierto :-) ), y otras tantas
cosas más.
Los tiempos luego cambiaron, pero algunas cosas no: las reglas y los
obstacúlos para participar en IETF jamas fueron los mismos para quienes
veniamos del c* del mundo -- o, mejor dicho, para quienes no
pertenecemos a la comunidad dominante de IETF (ver
https://datatracker.ietf.org/doc/html/draft-gont-diversity-analysis-00).
En todo este tiempo, Diego Maradona fue un motivador imprescindible...
en particular ante situaciones adversas.
A poco mas de tres meses de habernos dejado físicamente, mi guiño
(https://www.rfc-editor.org/rfc/rfc8981.html#name-authors-addresses ) a
quien fuera distinguido como "Maestro Inspirador de los Soñadores"
[Oxford] [Forbes].
La vida no es la misma sin el Diego.

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

Title: Temporary Address Extensions for Stateless
Address Autoconfiguration in IPv6 Author: F. Gont,

Status: Standards Track
Stream: IETF

URL: https://www.rfc-editor.org/info/rfc8981
DOI: 10.17487/RFC8981
This document describes an extension to IPv6 Stateless Address
Autoconfiguration that causes hosts to generate temporary addresses
with randomized interface identifiers for each prefix advertised with
autoconfiguration enabled. Changing 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 host. Additionally, it reduces the window of
exposure of a host as being accessible via an address that becomes
revealed as a result of active communication. This document obsoletes
RFC 4941.
This document is a product of the IPv6 Maintenance Working Group of the
IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for
the standardization state and status of this protocol. Distribution of
this memo is unlimited.
