Identifier-Locator Network Protocol
The Identifier-Locator Network Protocol (ILNP) is a network protocol that divides the two functions of network addresses, namely the identification of network endpoints, and assisting routing, by separating topological information from node identity. ILNP is backwards-compatible with existing Internet Protocol functions, and is incrementally deployable.
