The .NET Framework offers a number of types that makes accessing resources on the network easy to use.

To perform a simple ping, we will need to use the System.Net, System.Net.Network.Information, System.Text namespaces.

imports System.Net;
imports System.Net.NetworkInformation;
imports System.Text;

We'll put our code in the btnSubmit_Click() event.

When the btnSubmit_Click() event fires it creates a new Ping object. We can then execute the Send method of this object to send a ping to the host specified in our text box. Executing this method also returns a PingReply object which we can use to gather information such as the Address, Roundtrip Time, TTL, and Buffer Size.

Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click

Try
lblStatus.Text = ""
Dim ping As Ping = New Ping()
Dim pingreply As PingReply = ping.Send(txtHost.Text)
txtPing.Text &= "Address: " & pingreply.Address.ToString() & Constants.vbCr
txtPing.Text &= "Roundtrip Time: " & pingreply.RoundtripTime & Constants.vbCr
txtPing.Text &= "TTL (Time To Live): " & pingreply.Options.Ttl & Constants.vbCr
txtPing.Text &= "Buffer Size: " & pingreply.Buffer.Length.ToString() & Constants.vbCr

Catch err As Exception

lblStatus.Text = err.Message

End Try

The front end .aspx page looks something like this:

<tr>

<td width="100" align="right" bgcolor="#eeeeee" class="header1">Hostname/IP:</td>
<td align="center" bgcolor="#FFFFFF">
<asp:TextBox ID="txtHost" runat="server"></asp:TextBox>
  
<asp:Button ID="btnSubmit" runat="server" OnClick="btnSubmit_Click" Text="Submit" /></td>

</tr>
<tr>

<td width="100" align="right" bgcolor="#eeeeee" class="header1">Ping Results:</td>
<td align="center" bgcolor="#FFFFFF">
<asp:TextBox ID="txtPing" runat="server" Height="66px" TextMode="MultiLine" Width="226px"></asp:TextBox> <br />
<asp:label ID="lblStatus" runat="server"></asp:label></td>

</tr>

</table>

The flow for the code behind page is as follows:

Imports System.Net
Imports System.Net.NetworkInformation
Imports System.Text
Partial Public Class _Default : Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

End Sub

Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click

lblStatus.Text = err.Message

End Try

End Sub
End Class
