RFC 3849: IPv6 Address Prefix Reserved for Documentation

Still current, but amended. Parts of this document are changed or extended by RFC 9637. Read both.

In plain English — editorial summary, not part of the RFC

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.
