1.0 Introduction 1.0 Introduction
This document defines an IPv6 aggregatable global unicast address This document defines an IPv6 aggregatable global unicast address
format for use in the Internet. The address format defined in this format for use in the Internet. The address format defined in this
document is consistent with the IPv6 Protocol [IPV6] and the ''IPv6 document is consistent with the IPv6 Protocol [IPV6] and the ''IPv6
Addressing Architecture'' [ARCH]. It is designed to facilitate Addressing Architecture'' [ARCH]. It is designed to facilitate
scalable Internet routing. scalable Internet routing.
This documented replaces RFC 2073, ''An IPv6 Provider-Based Unicast This documented replaces RFC 2073, ''An IPv6 Provider-Based Unicast
Address Format''. RFC 2073 will become historic. Address Format''. RFC 2073 will become historic. The Aggregatable
Global Unicast Address Format is an improvement over RFC 2073 in a
number of areas. The major changes include removal of the registry
bits because they are not needed for route aggregation, support of
EUI-64 based interface identifiers, support of provider and exchange
based aggregation, separation of public and site topology, and new
aggregation based terminology.

2.0 Overview of the IPv6 Address 2.0 Overview of the IPv6 Address
IPv6 addresses are 128-bit identifiers for interfaces and sets of IPv6 addresses are 128-bit identifiers for interfaces and sets of
interfaces. There are three types of addresses: Unicast, Anycast, interfaces. There are three types of addresses: Unicast, Anycast,
and Multicast. This document defines a specific type of Unicast and Multicast. This document defines a specific type of Unicast
