在现实世界中，Apple iOS 在逐个应用程序的基础上默认为仅 IPv6 吗? [英] Is Apple iOS defaulting to IPv6-only, on an app-by-app basis, in the real world?

问题描述

Apple 的 iOS App Store 审核流程现在包含一项要求，即应用应在仅支持 IPv6 的网络上运行.

Apple's iOS App Store review process now includes a requirement that apps should work on IPv6 only networks.

考虑到这一点，Apple 是否会在逐个应用程序的基础上，为通过移动网络连接的 iPhone 在现实世界中默认使用 IPv6(不仅仅是在审核中)?

With that in mind, is Apple defaulting to IPv6-only, on an app-by-app basis, for iPhones connected over mobile networks in the real world (not just in review)?

即Apple 现在是否会强制通过 IPv6 审查的应用在现实世界中转向仅支持 IPv6?

I.e. is Apple now forcing the move to IPv6-only in the real world for apps that pass it's IPv6 review?

(对上述问题的任何答案本身都会很好，但对于那些有深入了解的人来说，跟进:UDP 数据包是否可以正确路由到/从 IPv6 移动设备路由到 IPv4 服务器通过蜂窝网络上的 NAT64?实际上是这个问题导致我想到了最初的问题，我想知道 TURN 客户端是否使用 TCP 而不是 UDP，因为 UDP 没有通过 IPv6->NAT64->IPv4).

(Any answer to the above question(s) would be great by itself, but for those with in-depth knowledge, a follow-up: Would UDP packets be properly routed to/from an IPv6 mobile device to an IPv4 server via NAT64 on the cellular network? It's actually this concern that leads me to the original question, I'm wondering if TURN clients are using TCP instead of UDP because UDP is not making it through IPv6->NAT64->IPv4).

推荐答案

Apple 不会强制只支持 IPv6，但他们必须适应世界上正在发生的事情.越来越多的移动网络部署 NAT64，如果 Apple 上的应用程序无法在这些网络上运行，那么这可能会给 Apple 带来坏名声.因此，他们要求应用支持这样的网络.

Apple is not forcing IPv6 only support, but they have to adapt to what's happening in the world. More and more mobile networks deploy NAT64 and if apps on Apple would not work on those networks then that could give Apple a bad reputation. Therefore they require that apps support such a network.

应用商店中仍有一些应用在 IPv6 要求到位之前已经上传，因此它们可能会被破坏.目前这些应用程序被允许保留在应用程序商店中，但将来它们可能会被踢出.上次我问 Apple 时还没有决定.

There are still apps in the app store that have been uploaded before the IPv6 requirement was in place so they may be broken. At the moment those apps are allowed to stay in the app store, but in the future they might be kicked out. Last time I asked Apple hadn't decided over that yet.

UDP 应该通过 NAT64 工作，但这将取决于端口将保持打开多长时间等.这将取决于网络，而不是 Apple.

UDP should work through NAT64, but it will be implementation dependent how long ports will remain open etc. That will depend on the network, not on Apple.
