Does the unity WWW class (Unity - Scripting API: WWW), support IPV6? I see in the whats new (https://unity3d.com/unity/qa/patch-releases/4.6.8p1) that WebRequests get ipv6. When I search the scripting API for WebRequest I don’t get any results.
The used “Internet Protocol” version has no direct relation to the TCP protocol. A TCP packet might get transferred by a IPv4 or an IPv6 packet. Which version is supported dependson your operating system support. So yes, the WWW class “supports” IPv6.

According to 4.6.9f1 patch notes, now Unity3d completely supports IPv6.
