Apple now biases towards IPv6 with a 25ms delay on connections
Interestingly, they claim that IPv6 tends to be more reliable and has lower latency now:
Based on our testing, this makes our Happy Eyeballs implementation go from roughly 50/50 IPv4/IPv6 in iOS 8 and Yosemite to ~99% IPv6 in iOS 9 and El Capitan betas. While our previous implementation from four years ago was designed to select the connection with lowest latency no matter what, we agree that the Internet has changed since then and reports indicate that biasing towards IPv6 is now beneficial for our customers: IPv6 is now mainstream instead of being an exception, there are less broken IPv6 tunnels, IPv4 carrier-grade NATs are increasing in numbers, and throughput may even be better on average over IPv6.
