Subject: [IPv6]Call for adoption: draft-iurman-6man-eh-occurrences-02 (Ends 2026-05-17)

[EXTERNAL] Verify links and attachments with sender.

This message starts a 6man WG Call for Adoption of:
draft-iurman-6man-eh-occurrences-02

This Working Group Call for Adoption ends on 2026-05-17

Abstract:
   Operational experience has demonstrated that permitting multiple
   occurrences of the same IPv6 Extension Header can create parsing
   ambiguity, complicate packet processing, and increase potential
   security risks.  Although RFC 8200 recommends that senders follow a
   specific order of appearance and limit the occurrences of Extension
   Headers, receivers cannot assume that these recommendations have been
   followed.  This document updates RFC 8200 by allowing an IPv6
   destination node, namely a host (i.e., the final destination of an
   IPv6 packet) or an intermediate destination node addressed by an
   entry in a Routing header list other than the final one, to enforce
   strict ordering and limits on the occurrence of Extension Headers.

Please reply to this message and indicate whether or not you support adoption of this Internet-Draft by the 6man WG. Comments to explain your preference are greatly appreciated. Please reply to all recipients of this message and include this message in your response.

Authors, and WG participants in general, are reminded of the Intellectual Property Rights (IPR) disclosure obligations described in BCP 79 [2].
Appropriate IPR disclosures required for full conformance with the provisions of BCP 78 [1] and BCP 79 [2] must be filed, if you are aware of any.
