Identifier/Locator Network Protocol

The Identifier/Locator Network Protocol (ILNP) (RFCs) is a network protocol designed to separate the two functions of network addresses, the identification of , and assisting routing by separating topological information from node identity.^[1] ILNP is backwards-compatible with existing IP, and is incrementally deployable.

ILNP itself is an architecture with two different instantiations at present.^[when?] ILNPv4 is ILNP engineered to work as a set of IPv4 extensions, while ILNPv6 is ILNP engineered as a set of IPv6 extensions.

At least three independent open-source implementations of ILNPv6 exist. University of St Andrews (Scotland) has a prototype in Linux/x86 and FreeBSD/x86, while Tsinghua U. (China) has a prototype in Linux/x86.

In February 2011, IRTF Routing Research Group (RRG) Chairs recommended that the IETF standardise ILNP (RFC 6115) as the preferred evolutionary direction for IPv6.

The University of St Andrews ILNP group is led by Prof. Saleem Bhatti. Other academics involved in continuing research include , and .
