Abstract

This document describes the issues surrounding the use of IPv6 site- local unicast addresses in their original form, and formally deprecates them. This deprecation does not prevent their continued use until a replacement has been standardized and implemented.

Abstract

   This document describes the issues surrounding the use of IPv6 site-

   local unicast addresses in their original form, and formally

   deprecates them.  This deprecation does not prevent their continued

   use until a replacement has been standardized and implemented.

1.  Introduction

   For some time, the IPv6 working group has been debating a set of

   issues surrounding the use of "site local" addresses.  In its meeting

   in March 2003, the group reached a measure of agreement that these

   issues were serious enough to warrant a replacement of site local

   addresses in their original form.  Although the consensus was far

   from unanimous, the working group confirmed in its meeting in July

   2003 the need to document these issues and the consequent decision to

   deprecate IPv6 site-local unicast addresses.

   Site-local addresses are defined in the IPv6 addressing architecture

   [RFC3513], especially in section 2.5.6.

   The remainder of this document describes the adverse effects of

   site-local addresses according to the above definition, and formally

   deprecates them.

RFC 3879            Deprecating Site Local Addresses      September 2004

   Companion documents will describe the goals of a replacement solution

   and specify a replacement solution.  However, the formal deprecation

   allows existing usage of site-local addresses to continue until the

   replacement is standardized and implemented.
