Apple has a bad app. "all apps must support IPv6" I use AVPlayer to play audio streaming and AFNetworking 3. ~ to load data.
link for audio stream http://more.fm:8000/more256 which contains ": 8080" port. This may be zarezhektino due to the fact that the port is registered in the link? I do not have the opportunity to test the application in the ipv6 network
