Scope of Applicability

LISP was originally developed to address the Internet-wide route scaling problem [RFC4984]. While there are a number of approaches of interest for that problem, as LISP has been developed and refined, a large number of other ways to use LISP have been found and are being implemented. As such, the design and development of LISP have changed so as to focus on these use cases. The common property of these uses is a large set of cooperating entities seeking to communicate over the public Internet or other large underlay IP infrastructures while keeping the addressing and topology of the cooperating entities separate from the underlay and Internet topology, routing, and addressing.
