获取真实IP

1.网上流传方法：

<%
Function GetIP()
GetIP = Request.ServerVariables("HTTP_X_FORWARDED_FOR")
If GetIP = "" or IsNull(GetIP) Then GetIP = Request.ServerVariables("REMOTE_ADDR")
End Function
%>

2.Dvbbs获取IP方法

<%
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)))
End Function

Function Checkstr(Str)
If Isnull(Str) Then
CheckStr = ""
Exit Function
End If
Str = Replace(Str,Chr(0),"")
CheckStr = Replace(Str,"'","''")
End Function
%>
