Not the same, but similar. Yes. But I think share64 on a WiFi network would require proxy ND, which doesn’t scale well, particularly if you have multiple unmanaged routers providing readability and transit. > I think that the use of ULA which is advertise to the "LAN" for reachability > does not have to be mutually exclusive with NAT64 for "cloud" reachability. Absolutely. That’s what we’re thinking for the ipv4 and dual stack cases. Doesn’t work for v6-only. > Since your document does not actually require any new protocol, but just > explains how to do something new using existing mechanism, I think that it > would fit into the current IOTOPS charter. I don’t think this is IoT-specific.

I don’t get a mental picture from this of how it helps. FWIW, Apple is now shipping a product (HomePod Mini) that does stub network routing for thread networks, and there’s also an open source implementation. Right now it only does the ULA solution. I’ll be writing a draft that describes this soon.
