           Attribution Option for Extension Header Insertion
                    draft-herbert-6man-eh-attrib-00

Abstract

   This document defines an IPv6 Hop-by-Hop Option that provides
   attribution for IPv6 extension headers inserted by intermediate nodes
   in the delivery path of a packet. The purpose of this option is
   twofold: first it identifies the extension headers that have been
   inserted, secondly it attributes the inserted extension headers to
   the node responsible for inserting them.
