using System;
using System.Net.NetworkInformation;

namespace ICMP_Listener
{
    class Program
    {
        static void Main(string[] args)
        {
            Ping pingSender = new Ping();
            string host = "www.example.com";

            try
            {
                PingReply reply = pingSender.Send(host);
                if (reply.Status == IPStatus.Success)
                {
                    Console.WriteLine("Address: {0}", reply.Address.ToString());
                    Console.WriteLine("RoundTrip time: {0}", reply.RoundtripTime);
                }
                else
                {

                }
            }
            catch (PingException ex)
            {
                Console.WriteLine("Ping failed: {0}", ex.ToString());
            }
