Internet Engineering Task Force (IETF) J. Laganier Request for Comments: 8005 Luminate Wireless, Inc. Obsoletes: 5205 October 2016 Category: Standards Track ISSN: 2070-1721 Host Identity Protocol (HIP) Domain Name System (DNS) Extension Abstract This document specifies a resource record (RR) for the Domain Name System (DNS) and how to use it with the Host Identity Protocol (HIP). This RR allows a HIP node to store in the DNS its Host Identity (HI), the public component of the node public-private key pair; its Host Identity Tag (HIT), a truncated hash of its public key (PK); and the domain names of its rendezvous servers (RVSs). This document obsoletes RFC 5205. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF).

Introduction This document specifies a resource record (RR) for the Domain Name System (DNS) [RFC1034] and how to use it with the Host Identity Protocol (HIP) [RFC7401]. This RR allows a HIP node to store in the DNS its Host Identity (HI), the public component of the node public- private key pair; its Host Identity Tag (HIT), a truncated hash of its HI; and the domain names of its rendezvous servers (RVSs) [RFC8004]. Currently, most of the Internet applications that need to communicate with a remote host first translate a domain name (often obtained via user input) into one or more IP addresses.
