This document presents real-world data regarding the extent to which
packets with IPv6 Extension Headers (EHs) are dropped in the Internet
(as originally measured in August 2014 and later in June 2015, with
similar results) and where in the network such dropping occurs. The
aforementioned results serve as a problem statement that is expected
to trigger operational advice on the filtering of IPv6 packets
carrying IPv6 EHs so that the situation improves over time. This
document also explains how the results were obtained, such that the
corresponding measurements can be reproduced by other members of the
community and repeated over time to observe changes in the handling
of packets with IPv6 EHs.
This document is a product of the IPv6 Operations Working Group of the IETF.
