Hi Brian, Thanks for the review. I wanted to clarify three points that you raised and I will ask the authors take care of the rest.

I think this is precisely the reason that the mechanism for putting the HOST_ID in the IP-ID is a non-starter. > 11.

This technique involves the translator (and not the sender) setting the IP-ID field. That is why it can still work with OSes on senders setting the IP-ID to zero.
