A Method for Generating Semantically Opaque Interface Identifiers with IPv6 Stateless Address Autoconfiguration (SLAAC)
draft-ietf-6man-stable-privacy-addresses-17
Technical Summary:
This document specifies a method for generating IPv6 Interface
Identifiers to be used with IPv6 Stateless Address Autoconfiguration
(SLAAC), such that addresses configured using this method are stable
within each subnet, but the Interface Identifier changes when hosts
move 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 MAC addresses), such that the benefits of
stable addresses can be achieved without sacrificing the 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 addresses.
Working Group Summary:
This document was sent back to the working group based on the number of
comments received during the IETF last call. The current document is
significantly improved. After a long discussion, another working
group last call was done with support from the w.g. The chairs had two
reviewers, Ray Hunter and Mark Smith, did a detailed review of the
draft. This resulted in several changes in the current draft (-14).
The reviewers have told us that the new draft resolves the issues they
raised. The w.g. chairs believe the draft is ready to send to the IESG
again.
In addition Alissa Cooper revised the document and is working on a draft
that provides an overview of the privacy considerations with all types of
IPv6 addresses.
