As of January 2009, the RIPE NCC has been involved in experimental inter-domain routing protocol trials. The Internet Architecture Board's (IAB) Routing and Addressing Workshop, held in 2006, renewed interest in the design of a scalable routing and addressing architecture for the Internet. The key issues driving this interest included concerns about the scalability of the routing system and the impending exhaustion of IPv4 address space.
Since the IAB workshop, several proposals that attempt to address the concerns expressed both at the workshop and in other forums have emerged. All of these proposals are based on a common concept: the separation of Locator and Identifier in the numbering of Internet devices, often termed the "Loc/ID split". The RIPE NCC's trial focuses on one proposal for implementing this concept, the Locator/Identifier Separation Protocol (LISP).
