title: IPV6-only issues
body: <p>Apple announced ipv6-only policy few days ago at <a href="https://developer.apple.com/news/?id=05042016a" rel="nofollow">https://developer.apple.com/news/?id=05042016a</a>.</p>
  
  <p>Is this applicable to apps targeting to only iOS9 or lower versions?</p>
  
  <p>I am using IPV4 address directly for HTTP request as <a href="http://x.x.x.x/path" rel="nofollow">http://x.x.x.x/path</a> (Assume that I have to use address instead of host name, please do not argue about this point). It can be synthesized to IPV6 address by using NSURLConnection with IOS 9.2, but fails for lower IOS version.</p>
