運行環境，NT（SERVER、WORKSTATION）、W2K 服務器上需要安裝WSH2.0或者更高版本 如果您的系統目前沒有安裝WSH2.0，您可以從以下這個地址去下載它 http://www.microsoft.com/msdownload/vbscript/scripting.asp 里面包含了WSH2.0 下面是源代碼 %@ Language="VBScript" %> % Option Explicit %> % If Request.Form("frmHost") = "" Then '設置初始值 strIP = Request.ServerVariables("REMOTE_ADDR") Else strIP = Request.Form("frmHost") End If %> html> head> title>DNS Lookup [v 1.0]/title> /head> 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" value="Lookup" onClick="document.frmRDNS.submit()"> /form> font face="arial" size="2" color="#003366"> % 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 ' See 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 While Not oTF.AtEndOfStream Data = Trim(oTF.Readline) If i > 2 Then ' Don't want to display 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 %> /font> /body> /html> 代碼很簡單，我不多說了，如果您對WSH有什么疑問的話，請去下載WSH的電子文檔中文版本的，CHINAASP下載區就有的吧 希望能對你有所幫助。
