Host Identity Protocol Distributed Hash Table Interface
Abstract
This document specifies a common interface for using the Host
Identity Protocol (HIP) with a Distributed Hash Table (DHT) service
to provide a name-to-Host-Identity-Tag lookup service and a Host-
Identity-Tag-to-address lookup service.

1. Introduction
The Host Identity Protocol (HIP) [RFC5201] may benefit from a lookup
service based on Distributed Hash Tables (DHTs). The Host Identity
namespace is flat, consisting of public keys, in contrast to the
hierarchical Domain Name System (DNS). These keys are hashed and
prefixed to form Host Identity Tags (HITs), which appear as large
random numbers. As the current DNS system has been heavily optimized
for address lookup, it may be worthwhile to experiment with other
services such as those defined here. DHTs manage such data well by
applying a hash function that distributes data across a number of
servers. DHTs are also designed to be updated more frequently than a
DNS-based approach. For an alternative method of using HITs to look
up IP addresses using DNS, see [HIT2IP].
One freely available implementation of a DHT is the Bamboo DHT, which
is Java-based software that has been deployed on PlanetLab servers to
form a free service named OpenDHT. OpenDHT was available via the
Internet for any program to store and retrieve arbitrary data.
OpenDHT used a well-defined Extensible Markup Language-Remote
Procedure Calling (XML-RPC) interface, featuring put, get, and remove
operations. OpenLookup, while not implemented as a DHT, is another
deployment of open source software compatible with this OpenDHT
interface. This document discusses a common way for HIP to use this
OpenDHT interface, so that various HIP experimenters may employ
lookup services in an interoperable fashion.
This document is a product of the HIP research group (RG) of the
IRTF. The HIP research group reached consensus that this interface
