There is a difference between “supporting” vs “deployment”, the first does not necessarily imply the second.

How does it work when you have a WiFi where you do not have any clue which device is connected? How do you understand that that particular device that just connect supports ILNPv6? If you can, do you need to create a dynamic DNS entry with the ILNP record? How can I tell other that they need to check that particular dynamic entry to contact me?

Thanks
