I am connected with my iPhone 6 / iOS 9.0 to an IPv6 network created following [this article][1]. When I take a look at the console of my device, I see

    Aug 11 12:15:07 titos-iPhone kernel[0] <Notice>: 076991.368570 wlan0.N[15305] checkIPv4AddressValidity@6178: Local IPv4  address 169.254.199.45

**Why do I see Received address 169.254.199.45 when I'm actually trying to connect to an IPv6 network?**

**How can I disable this behaviour and only receive an IPv6 address?**
