Abstract
This document provides an architecture for allocating IPv6 [1]
unicast addresses in the Internet. The overall IPv6 addressing
architecture is defined in [2]. This document does not go into the
details of an addressing plan.
1. Scope
The global internet can be modeled as a collection of hosts
interconnected via transmission and switching facilities. Control
over the collection of hosts and the transmission and switching
facilities that compose the networking resources of the global
internet is not homogeneous, but is distributed among multiple
administrative authorities. Resources under control of a single
administration within a contiguous segment of network topology form a
domain. For the rest of this paper, `domain' and `routing domain'
will be used interchangeably.
Domains that share their resources with other domains are called
network service providers (or just providers). Domains that utilize
other domain's resources are called network service subscribers (or
just subscribers). A given domain may act as a provider and a
subscriber simultaneously.
