yes, sect 4 of RFC 2460:

   A full implementation of IPv6 includes implementation of the
   following extension headers:

           Hop-by-Hop Options
           Routing (Type 0)
           Fragment
           Destination Options
           Authentication
           Encapsulating Security Payload

   The first four are specified in this document; the last two are
   specified in [RFC-2402] and [RFC-2406], respectively.

4.1  Extension Header Order

   When more than one extension header is used in the same packet, it is
   recommended that those headers appear in the following order:

           IPv6 header
           Hop-by-Hop Options header
           Destination Options header (note 1)
           Routing header
           Fragment header

Subject: Is there an official Extension Headers List?

Hello,

I just wonder if  any *official* summarization of currently existing IPv6 extension headers exists.
The only way I found to determine all headers is to step through the IANA protocol numbers list and check in the references whether the according protocol has a defined IPv6 extension header.
As far as I see it a complete current list would be:
Hop-by-Hop Option                       0
Routing Header                               43
Fragment Header                           44
AH                                                         51
ESP                                                        50
Destination Options                       60
Mobility Header                              135
Host Identity Protocol                   139
Shim6 Protocol                                140

Is there something I missed or misinterpreted? Or is there actually an official list (a citable source would fit my needs best)?
Thanks in advance.

Cheers,

Stefan
