IPv6应用商店拒绝应用程序查询IPv4服务器

Question

My App for Iphone/Ipad connects to a server, transmits data from this server by JSON and shows the data to the user in form of lists and graphs. The server in question " https://www.myfxbook.com " is not IPv6 compliant.

Apple's Appstore-review team keeps rejecting my app since they can't reach this server (which does not have an AAAA-record) within their test set-up.

I followed their advice to set up and test IPv6 connectivity in my place where I found that from my IPv6 network I could reach the IPv4-server. But obviously the Appstore-review team uses a pure IPv6 setup

using the "dig" command I found the following response within my NAT64 network

iMac:myfxtract XXXXXX$ dig -t AAAA https://www.myfxtract.com

; <<>> DiG 9.8.3-P1 <<>> -t AAAA https://www.myfxtract.com

If anyone has the same situation and could offer me some advice on the issue ? Been "talking" to Apple-hotlines for weeks to no avail...

Answer 1

The solution was to be resilient about the difference between testing within own NAT64 and the Appreview network. My app was finally accepted without further comment
