This document specifies a method for generating IPv6 Interface
Identifiers to be used with IPv6 Stateless Address Autoconfiguration
(SLAAC), such that an IPv6 address configured using this method is
stable within each subnet, but the corresponding Interface Identifier
changes when the host moves from one network to another. This method
is meant to be an alternative to generating Interface Identifiers
based on hardware addresses (e.g., IEEE LAN Media Access Control
(MAC) addresses), such that the benefits of stable addresses can be
achieved without sacrificing the security and privacy of users. The
method specified in this document applies to all prefixes a host may
be employing, including link-local, global, and unique-local prefixes
(and their corresponding addresses).
This document is a product of the IPv6 Maintenance Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
for improvements. Please refer to the current edition of the Internet
Official Protocol Standards (STD 1) for the standardization state and
