                Routing and Addressing in Networks with
                  Global Enterprise Recursion (RANGER)

Abstract

   RANGER is an architectural framework for scalable routing and
   addressing in networks with global enterprise recursion.  The term
   "enterprise network" within this context extends to a wide variety of
   use cases and deployment scenarios, where an "enterprise" can be as
   small as a Small Office, Home Office (SOHO) network, as dynamic as a
   Mobile Ad Hoc Network, as complex as a multi-organizational
   corporation, or as large as the global Internet itself.  Such
   networks will require an architected solution for the coordination of
   routing and addressing plans with accommodations for scalability,
   provider-independence, mobility, multihoming, and security.  These
   considerations are particularly true for existing deployments, but
   the same principles apply even for clean-slate approaches.  The
   RANGER architecture addresses these requirements and provides a
   comprehensive framework for IPv6/IPv4 coexistence.
