[Experimental .NET 4.6 Equivalent runtime] IPInterfaceProperties.GetIPv6Properties is not implemented
IPInterfaceProperties.GetIPv6Properties throws a NotImplementedException. This is necessary to retrieve the interface index of the network adapter on systems with multiple network interfaces for specifying the NIC used by multicast requests.
Steps to reproduce:
1. Open User's attached project
2. Play
Result: Error in the Console:
NotImplementedException: The method or operation is not implemented.
System.Net.NetworkInformation.UnixIPInterfaceProperties.GetIPv6Properties () (at <f044fe2c9e7e4b8e91984b41f0cf0b04>:0)

The Unity Blog Post 'Unity and IPv6 Support' by Mantas Puida states: "Finally, let us know if you encounter bugs in Unity related to IPv6. We will work hard to correct them as soon as possible."
This bug makes it impossible to do IPV6 UDP multicast on many systems yet it was closed as "Won't Fix" with no workaround suggested or anything. Perhaps Unity can revisit this bug.

Resolution Note:
Our class library implementation is inherited by mono, and this functionality has not been implemented upstream https://github.com/mono/mono . Unfortunately this functionality is not high enough priority for us to implement when triaging our bugs at this time.
