Re: Is there an official Extension Headers List?

However, extension headers defined since 2460 have to be added.
That's the case for MIPv6, SHIM6 and HIP.

This matters - there are known to be boxes that discard packets
with a SHIM6 header, for example.

We do maybe need a little normative RFC on this.
