IL2CPP Warning!

With IL2CPP, IPv6 is only supported on Unity 2018.3.6f1 and later because of this: Unity ChangeLog

IL2CPP: Added protocol support for IPv6 on Windows. (1099133)

IL2CPP: Correctly indicate that IPv6 is not supported on non-IPv6 platforms. (1108823)

Also, socket Reuse Address option isn't available in IL2CPP.
