Problem exporting solution to WebGL

Good morning,

I’m using Unity 5.3.3f1 Personal and into my code I have to use the Unity Ping class ( Unity - Scripting API: Ping ). The building and execution in internal Unity Player (attached image) runs properly. However when I try to export this solution to WebGL, I recieve the next error:

“error CS0246: The type or namespace name ‘Ping’ could not be found. Are you missing a using directive or an assembly reference?”

This is the C# source code with the related Ping code:

using UnityEngine;
using System.Collections;
using System.Text;
using System.Collections.Generic;
using LitJson;

public class PingScript : MonoBehaviour
{
    string Url = null, pingAddress = "192.168.0.180";

    float pingStartTime;
    
    // Use this for initialization
    void Start()
    {        
        CheckServerIp();
        if (Url == null)
        {                        
			pingAddress = "192.168.1.210";
            CheckServerIp();
        }
        print(Url);
    }

    // Update is called once per frame
    void Update()
    {
        if (Url != null)
        {
            //Do something
        }
    }

    void CheckServerIp()
    {
        bool internetPossiblyAvailable;
        switch (Application.internetReachability)
        {
            case NetworkReachability.ReachableViaLocalAreaNetwork:
                internetPossiblyAvailable = true;
                break;
            default:
                internetPossiblyAvailable = false;
                break;
        }
        if (!internetPossiblyAvailable)
        {
            Url = null;
        }
        Ping ping = new Ping(pingAddress);
        pingStartTime = Time.time;
        if (ping != null)
        {            
            if (ping.isDone)
            {                
                if (ping.time >= 0)
                {                    
                    Url = "http://" + pingAddress + ":3200/api/pumpvalues";
                }
            }
        }
    }
}

Kind regards.

According to the documentation, Unity’s WebGL only supports WWW and UnityWebRequest classes.
