It is available at: https://www.ietf.org/internet-drafts/draft-gont-6man-slaac-renum-08.txt This document proposes IPv6 SLAAC protocol updates to improve the robustness of SLAAC in the presence of renumbering events. 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: https://tools.ietf.org/rfcdiff?url2=draft-gont-6man-slaac-renum-08.txt As always, your feedback will be appreciated. Thanks!

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 URL: https://www.ietf.org/internet-drafts/draft-gont-6man-slaac-renum-08.txt Status: https://datatracker.ietf.org/doc/draft-gont-6man-slaac-renum/ Htmlized: https://tools.ietf.org/html/draft-gont-6man-slaac-renum-08 Htmlized: https://datatracker.ietf.org/doc/html/draft-gont-6man-slaac-renum Diff: https://www.ietf.org/rfcdiff?url2=draft-gont-6man-slaac-renum-08 Abstract: 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.
