iOS Question app rejected because of explicit IP?

[zak]

Hello. I wrote an app that in some mode connects to a server over the internet (on Bluehost) using HttpJob, PostString and then JobDone sub... and in another mode to an ESP8266 serially connected to a PIC, and operating as a client using the below command:
client.Connect("192.168.4.1", 5432, 4000)
All working flawlessly as expected.
However when I submitted my app to the apple store it got rejected:
"We discovered one or more bugs in your app when reviewed on iPad running iOS 11.0.3 on Wi-Fi connected to an IPv6 network."
could it be because of the explicit IP or the HttpJob? if so how to connect my Ipad to ESP8266 as a client and send data using astream.Write?

Don't be 100% sure that it is related to this ip address (though it is possible). Did they write what exactly happen? Did the app crash?

Erm... How can you be sure that the device will always be on that (internal) IP address?

He is connecting to the ESP8266 network and this is the default ip address.

It is true that you can provide an option to set a different ip address, including an Ipv6 address, if this is really the issue that caused your app to be rejected.
