I am posting here the code snippet to Ping a given IP address using c#.net

 

C#.net Section   -Sample.aspx.cs

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Net;
using System.Net.NetworkInformation;
using System.Text;

public partial class _Default : System.Web.UI.Page 
{
protected void Page_Load(object sender, EventArgs e)
{ 

}protected void btnSubmit_Click(object sender, EventArgs e)
{
try {
lblStatus.Text = null;
Ping ping = new Ping();
PingReply pingreply = ping.Send(txtHost.Text);
txtPing.Text += "Address: " + pingreply.Address + "\r";
txtPing.Text += "Roundtrip Time: " + pingreply.RoundtripTime + "\r";
txtPing.Text += "TTL (Time To Live): " + pingreply.Options.Ttl + "\r";
txtPing.Text += "Buffer Size: " + pingreply.Buffer.Length.ToString() + "\r";

}
catch (Exception err) {
lblStatus.Text = err.Message;



}

}

}

Here is the design section
