Abstract

To reduce the likelihood of conflict and confusion when relating documented examples to deployed systems, an IPv6 unicast address prefix is reserved for use in examples in RFCs, books, documentation, and the like. Since site-local and link-local unicast addresses have special meaning in IPv6, these addresses cannot be used in many example situations. The document describes the use of the IPv6 address prefix 2001:DB8::/32 as a reserved prefix for use in documentation.

Abstract

   To reduce the likelihood of conflict and confusion when relating

   documented examples to deployed systems, an IPv6 unicast address

   prefix is reserved for use in examples in RFCs, books, documentation,

   and the like.  Since site-local and link-local unicast addresses have

   special meaning in IPv6, these addresses cannot be used in many

   example situations.  The document describes the use of the IPv6

   address prefix 2001:DB8::/32 as a reserved prefix for use in

   documentation.

1.  Introduction

   The address architecture for IPv6 [1] does not specifically allocate

   an IPv6 address prefix for use for documentation purposes.

   Documentation material is currently using address prefixes drawn from

   address blocks already allocated or assigned to existing

   organizations or to well known ISPs, or drawn from the currently

   unallocated address pool.  Such use conflicts with existing or future

   allocations or assignments of IPv6 address space.

   The problems such conflicts may cause have already been encountered

   with IPv4 where literal use of documented examples in a production

   environment causes address and routing conflicts with existing

   services.  In making an explicit allocation of a documentation

   address prefix, it is intended that such operational problems may be

   avoided for IPv6.
