最简单的用以下语句:

ip=request.ServerVariables("REMOTE_ADDR")
response.Write(ip)
但这种方法对代理服务器上网的就不准了,故比较全面的是用下面的方法:

复制代码 代码如下:
<%PrivateFunctiongetIP()
DimstrIPAddr
IfRequest.ServerVariables("HTTP_X_FORWARDED_FOR")=""ORInStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"),"unknown")>0Then
strIPAddr=Request.ServerVariables("REMOTE_ADDR")
ElseIfInStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"),",")>0Then
strIPAddr=Mid(Request.ServerVariables("HTTP_X_FORWARDED_FOR"),1,InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"),",")-1)
ElseIfInStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"),";")>0Then
strIPAddr=Mid(Request.ServerVariables("HTTP_X_FORWARDED_FOR"),1,InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"),";")-1)
Else
strIPAddr=Request.ServerVariables("HTTP_X_FORWARDED_FOR")
EndIf
getIP=Trim(Mid(strIPAddr,1,30))
EndFunction
ip=getIP()
response.write(ip)
%>
