Ballot Text

Technical Summary

   The ICMP Extension Structure does not have a length field.
   Therefore, unless the length of the Extension Structure can be
   inferred from other data in the ICMP message, the Extension Structure
   must be the last item in the ICMP message.

   This document defines a length field for the ICMP Extension
   Structure.  When length information is provided, receivers can use it
   to parse ICMP messages.  Specifically, receivers can use length
   information to determine the offset at which the item after the ICMP
   Extension Structure begins.

   This document updates RFC 4884.
