[Azael Fernandez Alcantara]

Buen Dia,

Les retransmito esta info.

Seria importante desde nuestra region pudieran aportar en esta fase de 
experimentacion, y analizar por ejemplo las mejoras de seguridad 
mencionadas.

SALUDOS

In customer sites having IPv4-only Customer Premises Equipment (CPE),
Teredo (RFC 4380, RFC 5991, RFC 6081) provides last-resort IPv6
connectivity.  However, because it is designed to work without the
involvement of Internet Service Providers, it has significant
limitations (connectivity between IPv6 native addresses and Teredo
addresses is uncertain; connectivity between Teredo addresses fails
for some combinations of NAT types).  6a44 is a complementary
solution that, being based on ISP cooperation, avoids these
limitations.  At the beginning of 6a44 IPv6 addresses, it replaces
the Teredo well-known prefix, present at the beginning of Teredo IPv6
addresses, with network-specific /48 prefixes assigned by local ISPs
(an evolution similar to that from 6to4 to 6rd (IPv6 Rapid Deployment
on IPv4 Infrastructures)).  The specification is expected to be
complete enough for running code to be independently written and the
solution to be incrementally deployed and used.  This document is not
an Internet Standards Track specification; it is published for
examination, experimental implementation, and evaluation.
