Hi, Thanks for the report. I have a few comments. Le 19/06/2015 23:46, David Schinazi a écrit : [...] > *) Personal hotspot on iOS If your iPhone has dual-stack connectivity > on its cellular network, the hotspot it creates will be dual-stack as > well. The phone will share its prefix with Wi-Fi clients. The way of sharing a prefix with the Wi-Fi Clients is supposedly the one documented in RFC7278 "Extending an IPv6 /64 Prefix from a Third Generation Partnership Project (3GPP) Mobile Interface to a LAN Link" https://tools.ietf.org/html/rfc7278 That is straightforward to implement yet it does have some drawbacks. The most important drawback of 64share IMHO is that the smartphone can not make two hotspots simultaneouly: one on WiFi and one on Bluetooth. Or otherwise one on WiFi5GHz and one on WiFi2.4GHz. Or several subnets in a car connected with an Apple phone to the Internet. Because it is impossible to share a unique /64 prefix to more than just one subnet. It is better to tell the operator to provide a /63 to smartphones (not a /64), with DHCPv6 Prefix Delegation. That will fix it. > *) Internet Sharing on the Mac Today, regular internet sharing (from > your ethernet to Wi-Fi for example) does not support IPv6 because of > the limited use cases, and the lack of demand for it. If you get done the above then you get Internet Sharing on the Mac Today as well, for free. > *) Internet Sharing on the Mac - NAT64 testing mode The NAT64 test > mode was designed to help developers ensure that their app can still > function with IPv6-only NAT64+DNS64 connectivity and communicate with > their IPv4 server, even if the developer does not have access to the > IPv6 internet.

This implementation detail could change in the future. Makes sense.
