FYI: <https://www.rfc-editor.org/info/rfc7872>

Nadie ha hecho tanto como dos personas, Guillermo Gont y Nelida Garcia,
para que que la región tenga los RFCs (pocos o muchos) que tiene. La
ayuda ha sido en tantos aspectos (siempre empezando por un "que
necesitas?"/"en que te puedo ayudar?"), que sería imposible la
enumeración. El agradecimiento en el RFC, da cuenta de ello:

   Fernando Gont would like to thank Nelida Garcia and Guillermo Gont
   for their love and support.

Hoy es también un dia especial, dado que se cumplen 30 años de que,
quien considero mi mentor, "escribiera" dos obras de arte que, sumadas
al contexto, dejan en evidencia su genialidad y su magia ("estar en el
momento que hay que estar").

P.S.: Si te preguntas porque el titulo del RFC hace referencia al "Real
World", es porque el documento se apoya en datos/mediciones, y no en
expresiones de deseo.

This document presents real-world data regarding the extent to which
packets with IPv6 Extension Headers (EHs) are dropped in the Internet
(as originally measured in August 2014 and later in June 2015, with
similar results) and where in the network such dropping occurs.  The
aforementioned results serve as a problem statement that is expected
to trigger operational advice on the filtering of IPv6 packets
carrying IPv6 EHs so that the situation improves over time.  This
document also explains how the results were obtained, such that the
corresponding measurements can be reproduced by other members of the
community and repeated over time to observe changes in the handling
of packets with IPv6 EHs.

This document is a product of the IPv6 Operations Working Group of the IETF.
