Hi, this draft has been updated based on feedback from the IETF120 6MAN and MANET working
group sessions where the work was presented. The updates include:

  - Drop support for fec0::/10 - reason: RFC3879 deprecation has rendered this prefix inoperable
  - Use prefix 2001:20::/28 [RFC7343][RFC7401] as "Type-1" Multilink-Local Address (MLA) prefix
  - Use prefix 2001:30::/28 [RFC9374] as "Type-2" MLA prefix
  - Allow future documents to define new MLA types, if necessary

While MANETs represent a natural basic use case, the IPv6 Ad Hoc network addressing
scheme applies to all manners of IPv6 networks and not just those that fall within the auspices
of the MANET working group. The work is therefore in scope for the larger Internet area in
general the same as RFC5889, but is more specifically targeted for 6MAN due to its exclusive
focus on IPv6. For full context, please view the IETF120 MANET session presentation beginning
at the 22minute mark here:

https://play.conf.meetecho.com/Playout/?session=IETF120-MANET-20240726-1630

Please review and comment so that this essential work can move forward.

Thank you - Fred Templin

   Title:   IPv6 Addresses for Ad Hoc Networks
   Author:  Fred L. Templin
   Name:    draft-templin-6man-mla-19.txt
   Pages:   13
   Dates:   2024-08-01

Abstract:

   Ad Hoc networks often present a challenging environment for IPv6
   addressing due to the indeterminant neighborhood properties of their
   interfaces.  IPv6 nodes must assign IPv6 addresses to their interface
   connections to Ad Hoc networks that are locally unique but must not
   be propagated to other networks.  IPv6 nodes must therefore be able
   to assign self-generated addresses to their interfaces when there are
   no IPv6 Internetworking routers present that can coordinate topology-
   relative IPv6 addresses or prefixes.  This document specifies IPv6
   address types that can be assigned to Ad Hoc network interfaces.
