[IPv6]Re: Reclaiming fec0::/10 (I-D Action: draft-templin-6man-mla-01.txt)

["Templin (US), Fred L" <[e-mail]>]

Hi Bob, following the IANA considerations RFC3879 goes on to say:

“7.  Acknowledgements

   The authors would like to thank Fred Templin”

I take that along with the IANA text as an indication that fec0::/10 was set aside for
someone (possibly even Fred Templin!) to come back at a future time and reclaim
the address block. So, 21 years later I am here now to collect.

Thank you - Fred

Fred,

Proposing a new type of scoped IPv6 addresses is fine.   IMHO, there would need to be a lot of justification to warrant that in order to build a consensus in 6MAN and the IETF.

It is extremely premature to discuss what prefix to use for it at this point.

Bob

p.s. I note your draft has no references to any other MANET work, nor any mention of a new addressing scope.

Hi Eric,

RFC3879 IANA considerations says:

   “IANA is requested to mark the FEC0::/10 prefix as "deprecated",
   pointing to this document.  Reassignment of the prefix for any usage
   requires justification via an IETF Standards Action [RFC2434].”

The -templin draft (now at version -02) has been re-scoped to Standards Track although
its IANA considerations are currently NULL:

https://datatracker.ietf.org/doc/draft-templin-6man-mla/

But, the key thing to realize about this draft is that it proposes a new addressing
scope for the IPv6 scoped addressing architecture. The addressing scopes are:


  *   Link-local Addresses
  *   MANET Local Addresses (formerly site-local)
  *   Unique Local Addresses
  *   Global Unicast Addresses

And, all of these address scopes have their essential uses in the architecture.

Thank you - Fred

As an individual contributor (and neither a positive not negative opinion on the draft itself), I think it is rather IANA job to do this kind of allocation.

Hi, regarding this debate about the various IPv6 prefixes that may or may not be used
for IPv6 MANET Local Addresses (MLAs), a simple and obvious answer is why not just
reclaim the prefix fec0::/10 (formerly site-local and deprecated by RFC3879)?

This new draft version therefore requests reinstatement of fec0::/10 in a new role
as the top-level prefix for IPv6 MLAs while rendering RFC3879 obsolete.

   Title:   IPv6 MANET Local Addresses (MLAs)

Abstract:

   Mobile Ad-hoc NETworks (MANETs) present an interesting challenge for
   IPv6 addressing due to the indeterminant neighborhood properties of
   MANET interfaces.  MANET routers must assign an IPv6 address to each
   MANET interface that is both unique and routable within the MANET but
   must not be forwarded to other networks.  MANET routers must be able
   to assign self-generated addresses when there is no infrastructure
   present on the link that can delegate topology-relative IPv6
   addresses or prefixes.  This document therefore specifies a means for
   MANET routers to generate and assign MANET Local Addresses (MLAs).
