I saw this question in Classic ASP but I want this answer in ASP.NET.
Get hostname from IP.
Is there any way in ASP.NET to resolve a hostname from a given IP address? (in VB.NET)
Thank you.

<%@ Import Namespace="System.Net" %>
<Script runat="Server">
Sub Button_Click( s As Object, e As EventArgs )
Dim objIPHostEntry As IPHostEntry
objIPHostEntry = Dns.GetHostByAddress( txtIP.Text )
lblHostName.Text = objIPHostEntry.HostName
End Sub
</Script>
<html>
<head><title>Dns.aspx</title></head>
<form runat="Server">
<h2>Enter an IP Address:</h2>
<asp:TextBox
id="txtIP"
Runat="Server" />
<asp:Button
Text="Submit!"
OnClick="Button_Click"
Runat="Server" />
<p>
<asp:Label
id="lblHostName"
EnableViewState="False"
Runat="Server" />
</form>
</body>
</html>

Hello stu9820
Thanks for your reply. But when I tried out your code the label is blank. It doens't return the hostname of the IP address I entered. What could be wrong?
