Creo que esto puede ser de utilidad para tomar en cuenta al momento de
hacer sus planes de direccionamiento de IPv6.
Como dato, este RFC y BCP sustituyen al RFC 3177.

RFC 3177 argued that in IPv6, end sites should be assigned /48 blocks
in most cases.  The Regional Internet Registries (RIRs) adopted that
recommendation in 2002, but began reconsidering the policy in 2005.
This document obsoletes the RFC 3177 recommendations on the
assignment of IPv6 address space to end sites.  The exact choice of
how much address space to assign end sites is an issue for the
operational community.  The IETF's role in this case is limited to
providing guidance on IPv6 architectural and operational
considerations.  This document reviews the architectural and
operational considerations of end site assignments as well as the
motivations behind the original recommendations in RFC 3177.  Moreover,
this document clarifies that a one-size-fits-all recommendation of /48 is
not nuanced enough for the broad range of end sites and is no longer
recommended as a single default.

This document obsoletes RFC 3177.  [STANDARDS-TRACK]
