Host Identity Protocol

The Host Identity Protocol (HIP) provides a method of separating the end-point identifier and locator roles of IP addresses. It introduces a new Host Identity (HI) name space, based on public keys. The public keys are typically, but not necessarily, self-generated.

HIP is being specified in the IETF's HIP working group. An IRTF HIP research group looks at the broader impacts of HIP.

The working group is chartered to produce RFCs on the "Experimental" track, but it is understood that their quality and security properties should match the standards track requirements. The main purpose for producing Experimental documents instead of standards track ones are the unknown effects that the mechanisms may have on applications and on the Internet in the large.
