I created a IPV6 environment reference by this article https://developer.apple.com/library/mac/documentation/NetworkingInternetWeb/Conceptual/NetworkingOverview/UnderstandingandPreparingfortheIPv6Transition/UnderstandingandPreparingfortheIPv6Transition.html#//apple_ref/doc/uid/TP40010220-CH213-SW16
In this environment the testing is useful
But,when i support my app to itunes connect, it was rejected because in IPV6 environment can not connect
how could it be? must we update server ?
