             Discovering Provisioning Domain Names and Data
               draft-ietf-intarea-provisioning-domains-00

Abstract

   An increasing number of hosts and networks are connected to the
   Internet through multiple interfaces, some of which may provide
   multiple ways to access the internet by means of multiple IPv6 prefix
   configurations.

   This document describes a way for hosts to retrieve additional
   information about their network access characteristics.  The set of
   configuration items required to access the Internet is called a
   Provisioning Domain (PvD).  The PvD is identified by a Fully
   Qualified Domain Name (FQDN).  This identifier, retrieved using a new
   Router Advertisement (RA) option, is associated with the set of
   information included within the RA and may later be used to retrieve
   additional information associated with the PvD by way of an HTTP-
   over-TLS request.

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
