Technical Summary
This document summarizes the operational implications of IPv6
extension headers specified in the IPv6 protocol specification
(RFC8200), and attempts to analyze reasons why packets with IPv6
extension headers are often dropped in the public Internet.
Working Group Summary
One point of contention observed during the IETF LC (and
had been discussed during the WG evolution of this document)
regarded the document scope. Some participants felt that the
document should include more empirical data about the use
and support of IPv6 extension headers in the Internet, potentially including
information from vendors on what they support, to allow guidance
to be given to end host developers as to how IPv6 extension headers
can be successfully used. The rough consensus was that this
issue is outside the scope of this document. Of course, it could be
tackled by future work.
Document Quality
The document has been developed in the WG for quite a
while, has had a lot of discussion, and has been reviewed
by a good number of WG participants.
Personnel
Ron Bonica is the document shepherd.
Rob Wilton is the area director.
