Hi,

As per this news : https://developer.apple.com/news/?id=05042016a, developers need to add ipv6 only support from June, does this applies to low level POSIX sockets API too ? Which we are using it for real time video streaming and other signaling stuff (we dont use any HTTP transporting but TCP and UDP)

There’s no fundamental reason why you can’t support IPv6 is BSD Sockets code. However, this requirement is not about APIs, it’s about user-level functionality. Does your app work if you deploy it on a NAT64 IPv6-only network? If not, that’s something you need to investigate.

You can set up a test IPv6-only networking using the instructions in the docs referenced by the developer news article.

Does your app rely on hard coded IPs?

Sounds like a job for the next version of Network Link Conditioner - someone should file a request 😉

Is it right that my app must run well in IPv6-only network on iOS 9 or above, no need on ALL iOS versionn?
