I am trying to add my application on app store but it returns this error that my application not support ipv6 and people told me that i should create ipv6 network to test my app. now i have data on server but server which have this data doesn't support IPV6 only support IPV4 should it support IPV6 or it's ok to use IPV6 to get data from server that doesn't support IPV6
Your server can receive requests over IPv6 in two ways: 1) Your server support IPv6 and has IPv6 address (Also most hosting support this feature). 2) Some device (hardware or Linux router) in front of the server should support both IPv6 and IPv4. It will receive requests over IPv6 and transmit them to your server over IPv4.
You may try to answer Appstore, that your hosting provider on server side do not support IPv6. For my case It worked.
