IPv6 Address Prefix Reserved for Documentation
RFC 3849, “IPv6 Address Prefix Reserved for Documentation”, is an Informational document published in July 2004 by G. Huston, A. Lord, P. Smith. It has since been updated by RFC 9637. The canonical text is published by the RFC Editor.
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. This memo provides information for the Internet community.
