请高手指点，我如何才能获得客户端的IP呢，谢了

<%
Function getIP()
Dim strIPAddr
If Request.ServerVariables("HTTP_X_FORWARDED_FOR") = "" OR InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), "unknown") > 0 Then
strIPAddr = Request.ServerVariables("REMOTE_ADDR")
ElseIf InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ",") > 0 Then
strIPAddr = Mid(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), 1, InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ",")-1)
actforip=Request.ServerVariables("REMOTE_ADDR")
ElseIf InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ";") > 0 Then
strIPAddr = Mid(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), 1, InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ";")-1)
actforip=Request.ServerVariables("REMOTE_ADDR")
Else
strIPAddr = Request.ServerVariables("HTTP_X_FORWARDED_FOR")
actforip=Request.ServerVariables("REMOTE_ADDR")
End If
'getIP = CheckStr(Trim(Mid(strIPAddr, 1, 30)))
getip=strIPAddr
End Function
%>

收了 谢

多谢McroSoft了，不过又有新问题了，如何比较ip呢，我想实现的功能是判断客户端是否在所指定的IP内，求进一步指点了
