Rolf,

As a historical tidbit you may want to include in your draft. IPv6 supported reverse traceroute out of the box. Using RH0 and sending a packet to yourself via the destination. That code is probably still in stacks.

If anybody is interested, please reach out to me. Also, if people would like to run the client, there is a command line switch that will send us the result of a reverse traceroute run. We would appreciate, if you could run our client against one or more public instances of reverse traceroute, that would be great and use the switch to send us the measurement. So far there is only one public endpoint, but the list in the ENDPOINTS file in the above mentioned github repository will be updated, as more public endpoints come online.

The feedback from the operational community was very good and there is interest in the work. If you would like to hear about reverse traceroute and the things that drove our design, the talk was recorded and is available here:
