aspx vb.net获取真实IP的函数如下：
<script runat="server">
Public Function CheckIp(ByVal ip As String) As Boolean
Dim pat As String = "^[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}$"
Dim reg As Regex = New Regex(pat)
if ip = "" Then
CheckIp = False
exit Function
end if
CheckIp = reg.IsMatch(ip)
End Function Public Function get_cli_ip() As String
If ( Not( System.Web.HttpContext.Current.Request.ServerVariables("HTTP_CLIENT_IP") Is Nothing) And CheckIp(System.Web.HttpContext.Current.Request.ServerVariables("HTTP_CLIENT_IP")) = True) Then
get_cli_ip = System.Web.HttpContext.Current.Request.ServerVariables("HTTP_CLIENT_IP")
Exit Function
ElseIf Not(System.Web.HttpContext.Current.Request.ServerVariables("HTTP_X_FORWARDED_FOR") Is Nothing) Then
Dim ips() As String = Split(System.Web.HttpContext.Current.Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ",")
For i As Integer = 0 To ips.Length - 1
If CheckIp(Trim(ips(i))) = True Then
get_cli_ip = Trim(ips(i))
Exit Function
End If
Next
End If
get_cli_ip = System.Web.HttpContext.Current.Request.ServerVariables("REMOTE_ADDR")
End Function
</script>
