Folks, We are working in a revision of RFC4941 (temporary addresses), to address issues found in such spec -- for example, RFC4941 leads to the same interface identifiers being employed for different prefixes (which of course has privacy implications) The current version of the revised spec is available at: https://tools.ietf.org/html/draft-ietf-6man-rfc4941bis We'd really like to hear your comments and double-check if we got everything right, if there's something that we missed, etc. If possible, please post your feedback on the 6man list (https://www.ietf.org/mailman/listinfo/ipv6). But I'll be happy to receive comments here or unicast and relay them as necessary. Thanks! Cheers, Fernando -------- Forwarded Message -------- Subject: New Version Notification for draft-ietf-6man-rfc4941bis-03.txt Date: Thu, 05 Sep 2019 05:42:29 -0700 From: internet-drafts@ietf.org To: Fernando Gont <fgont@si6networks.com>, Suresh Krishnan <suresh.krishnan@ericsson.com>, Richard Draves <richdr@microsoft.com>, Thomas Narten <narten@us.ibm.com> A new version of I-D, draft-ietf-6man-rfc4941bis-03.txt has been successfully submitted by Fernando Gont and posted to the IETF repository. Name: draft-ietf-6man-rfc4941bis Revision: 03 Title: Privacy Extensions for Stateless Address Autoconfiguration in IPv6 Document date: 2019-09-05 Group: 6man Pages: 21 URL: https://www.ietf.org/internet-drafts/draft-ietf-6man-rfc4941bis-03.txt Status: https://datatracker.ietf.org/doc/draft-ietf-6man-rfc4941bis/ Htmlized: https://tools.ietf.org/html/draft-ietf-6man-rfc4941bis-03 Htmlized: https://datatracker.ietf.org/doc/html/draft-ietf-6man-rfc4941bis Diff: https://www.ietf.org/rfcdiff?url2=draft-ietf-6man-rfc4941bis-03 Abstract: Nodes use IPv6 stateless address autoconfiguration to generate addresses using a combination of locally available information and information advertised by routers. Addresses are formed by combining network prefixes with an interface identifier. This document describes an extension that causes nodes to generate global scope addresses with randomized interface identifiers that change over time. Changing global scope addresses over time makes it more difficult for eavesdroppers and other information collectors to identify when different addresses used in different transactions actually correspond to the same node. This document formally obsoletes RFC4941. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
