We follow the guideline to setup the IPv6 NAT64 environment to test our app works in the IPv6 NAT64 network.
In the iOS Wi-fi setting it shows DNS 2001:2:0:aab1::1 and IP address shows 169.254.61.21, which should be correct based on another thread from the reply of this thread: https://forums.developer.apple.com/message/140901#140901And our app works fine in the testing environment. However, our app still got rejected due to network problem in the reviewer's testing environement. We cannot replicate the problem and would like to post this to see if anybody having similar issue.
We use AFNetworking 3.1 to issue the HTTP requests and test for reachability, which should be based on NSURLSession and fully support IPv6. We grepped the code and are sure that we don't have any IPv4 address in the code base. We are thinking to do Packet Capture to debug our case, but in the meantime we would also like to ask here to see if anybody could point out that potentital root of cause of the rejection.
Thanks in advance.
