How to handle IPv4 Address literals for IPv6-only network in iOS8

Is there any way to handle the hardcoded IPv4 address literals (such as 172.1.2.3) in iOS8.x ?

As per the apple documentation,

- In iOS 9 and later, NSURLSession and CFNetwork automatically synthesizes IPv6 addresses from IPv4 literals locally on devices operating on DNS64/NAT64 networks.

- The ability to synthesize IPv6 addresses was added to getaddrinfo() in iOS 9.2.

But there is no mention of how to handle address literals for iOS8.x.
