UnityEngine.Ping does not work with ipv6 addresses



To Reproduce:

1. Open scene "Ping Test" in the attached project.
You need to be on an ipv6 network to test this ( can use if you're testing on ios/have a mac:

2. Run it and click on the "ping ipv6 address", observe that it fails with Ping.time = -1
(the address has ipv6 prefix, and can be pinged with ping6 util)

Tested on iOS and OSX

    This is still not fixed in 5.4.0f3 even though this post suggests so. Please re-open.

    Yup, I'm not sure how 5.3.5 is fully IPv6 ready without the Ping class?

    I have the same issue with Unity 5.3.5 even though it’s supposed to fully support IPv6.

    Is there any update with this issue?
