             Discovering Provisioning Domain Names and Data
               draft-ietf-intarea-provisioning-domains-02

Abstract

   An increasing number of hosts access the Internet via multiple
   interfaces or, in IPv6 multi-homed networks, via multiple IPv6 prefix
   configurations context.

   This document describes a way for hosts to identify such contexts,
   called Provisioning Domains (PvDs), where Fully Qualified Domain
   Names (FQDNs) act as PvD identifiers.  Those identifiers are
   advertised in a new Router Advertisement (RA) option and, when
   present, are associated with the set of information included within
   the RA.

   Based on this FQDN, hosts can retrieve additional information about
   their network access characteristics via an HTTP over TLS query.
   This allows applications to select which Provisioning Domains to use
   as well as to provide configuration parameters to the transport layer
   and above.
