Need to install WSH2.0 or later on the server
If your system does not currently have WSH2.0 installed, you can download it from the following address
Http://www.microsoft.com/msdownload/vbscript/scripting.asp
It contains WSH2.0.
Below is the source code
<%@ language= "VBScript"%>
<% Option Explicit%>
<%
If Request.Form ("frmhost") = "" Then
' Set the initial value
StrIP = Request.ServerVariables ("REMOTE_ADDR")
Else
StrIP = Request.Form ("Frmhost")
End If
%>
<title>dns Lookup [v 1.0]</title>
<body bgcolor= "#FFFFFF" >
<form method= "POST" name= "Frmrdns" >
<label for= "Frmhost" ><u>Host:</u></label>
<input type= "text" name= "Frmhost" id= "Frmhost"
Value= "<%= StrIP%>" >
<input type= "button" Name= "Btnsubmit" id= "btnsubmit"

Rmethod = UCase (Request.ServerVariables ("Request_method"))
If Rmethod = "POST" Then
' Lookup Host
Strreturn = NsLookup (StrIP)
If strreturn <> "" Then
Response.Write Strreturn
Else
' A Lame host is any Valid host that DNS cannot Resolve
' InterNIC for Details
Response.Write "<b>lame host-could not Resolve DNS for" _
& StrIP & "</b><br>"
End If
End If
Function NSlookup (Strhost)
' Create Shell Object
Set Oshell = Server.CreateObject ("Wscript.Shell")
' Run NSLookup via Command Prompt
' Dump Results into a temp text file
Oshell.run "%comspec%/C nslookup" & Strhost _
& "> C:\" & strhost & ". txt", 0, True
' Open the temp Text File and Read out the ' Data
Set OFS = Server.CreateObject ("Scripting.FileSystemObject")
Set OTF = Ofs.opentextfile ("C:\" & strhost & ". txt")
TempData = Null
Data = Null
i = 0
Do as not Otf.atendofstream
Data = Trim (otf.readline)
If i > 2 Then ' Don ' t want to display the local DNS Info.
TempData = tempdata & Data & "<BR>"
End If
i = (i + 1)
Loop
' Close it
Otf.close
' Delete It
Ofs.deletefile "C:\" & strhost & ". txt"
Set OFS = Nothing
NsLookup = TempData
End Function

</body>
The code is very simple, I do not say more, if you have any questions about WSH, please go to download WSH electronic documents
In the Chinese version, the chinaasp download area is available.
I hope I can be of some help to you.
