This document describes the Naming Delegation Architecture that makes
IPv6 Home Network globally reachable with Names or Fully Qualified
Domain Names (FQDN). In this architecture, the Customer Premise
Equipment (CPE) acts as the DNS Authoritative Server of the Home
Network also called the Delegated DNS Server. The Naming Delegation
is configured between the Delegated DNS Server and the Delegating DNS
Server managed by the ISP.
The use case considered in this document is an End User that
subscribes its ISP a specific Delegated Domain for its Home Network.
This document describes how the CPE automatically sets the Naming
Delegation between the Delegating and Delegated DNS Server.
The Naming Delegation is requested by the CPE. The CPE DHCP Client
and the ISP DHCP Server exchange DHCP Options to properly set the
Naming Delegation. More specifically, the CPE DHCP Client (resp. the
ISP DHCP Server) configures the DNS(SEC) Zones of the Delegated DNS
Server (resp. Delegating DNS Server). For the Delegating DNS Server,
the necessary pieces of information required to set the Naming
Delegation are the IP address of the Delegated DNS Server, and if
DNSSEC is used, the Delegation of Signing Information. For the
Delegated DNS Server, the necessary information is the Delegated
Domain associated to the Home Network.
