But I'll be happy to receive comments here or unicast and relay them as necessary. Thanks!

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.
