We have posted a revision of draft-gont-6man-slaac-renum. It is 
available at:

The main changes incorporated in this version are:

* We have eliminated the counter-based algorithm from Section 4.5

Previous revisions of the draft contained two alternative algorithms in 
Section 4.5: a counter-based algorithm, and a timer-based algorithm. The 
timer-based algorithm is more robust and simple, so it didn't make sense 
to keep the counter-based algorithm. (Kudos to Philip Homburg for 
"pushing" us to improve the algorithm).

* Clarified the terminology used in the document

This is a rather minor detail. We simply have spelled out that 
throughout the document, "GUAs" refer to "globally reachable" addresses 
(as opposed to ULAs).

The diff from the last rev is available at:

As always, your feedback will be appreciated.

A new version of I-D, draft-gont-6man-slaac-renum-08.txt
has been successfully submitted by Fernando Gont and posted to the
IETF repository.

Name:		draft-gont-6man-slaac-renum
Revision:	08
Title:		Improving the Robustness of Stateless Address Autoconfiguration 
(SLAAC) to Flash Renumbering Events
Document date:	2020-05-18
Group:		Individual Submission
Pages:		24

    In renumbering scenarios where an IPv6 prefix suddenly becomes
    invalid, hosts on the local network will continue using stale
    prefixes for an unacceptably long period of time, thus resulting in
    connectivity problems.  This document improves the reaction of IPv6
    Stateless Address Autoconfiguration to such renumbering scenarios.


Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at
