Strategy Mobile Application version 10.3 for iOS is supported for IPv6 (Internet Protocol version 6). Strategy mobile app uses NSURLsession which is a new network API from iOS 9.
IPv6 is a revision of the Internet Protocol (IP) developed by the Internet Engineering Task Force (IETF). IPv6 is intended to succeed IPv4, which is the dominant communications protocol for most Internet traffic. IPv6 was developed to deal with the problem of IPv4 running out of addresses. IPv6 implements a new addressing system that allows for far more addresses to be assigned than with IPv4.
Third party information: Apple Inc, announced the transition to IPv6-only network services in iOS 9. Starting June 1, 2016 all apps submitted to the App Store must support IPv6-only networking.
