用ASP做的DNS LOOKUP程序

运行环境，NT（SERVER、WORKSTATION）、W2K 服务器上需要安装WSH2.0或者更高版本如果您的系统目前没有安装WSH2.0，您可以从以下这个地址去下载它 http://www.microsoft.com/msdownload/vbscript/scripting.asp 里面包含了WSH2.0 下面是源代码 <%@ Language="VBScript" %> <% Option Explicit %> <% If Request.Form("frmHost") = "" Then '设置初始值 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> 代码很简单，我不多说了，如果您对WSH有什么疑问的话，请去下载WSH的电子文档中文版本的，CHINAASP下载区就有的吧希望能对你有所帮助。
