Dear Cameron, Thanks for your effort. Easy math version assuming the entire internet moves to this model of stateless address sharing: 50 Billion Internet nodes [1] As I said, I don't think we should consider Internet of things in this aspect. Quoting the paper: As an example of connected

Nejc, we indeed need some wordsmithing on that part of the text, but the message that it tries to convey looks unaffected: - If one believes that port unrestriced TCP provides enough security, then the port-restriction does little to alter that in consideration of host/CPE practices (no

Dear Wojciech, - If one believes that port unrestriced TCP provides enough security, then the port-restriction does little to alter that in consideration of host/CPE practices (no randomization). As you point out, such belief may be misplaced, especially with larger widow sizes. Granted, a

Tina, The problem with static allocation is that it cannot adapt quickly to subscriber demand. Exactly; so it cannot optimise the number of ports in use. What strikes me in this conversation is that all these solutions are a tremendous amount of work to deal with legacy equipment, and I have

Dear Simon, Yes, we've been discussing this internally among co-authors of draft-despres-softwire-4rd-addmapping. The conclusion was that the transport checksum does not need to be modified. OK. But this then means, that if there are any stateful devices like stateful firewalls, IPS/IDS
