循环遍历：

<%
Dim aa, ipList, ip, found
aa = Request.ServerVariables("REMOTE_ADDR")

ipList = Array("99.88", "110.52", "43.80.235", "11.9.67.180")
found = False

For Each ip In ipList
    If InStr(aa, ip) > 0 Then
        found = True
        Exit For
    End If
Next

If found Then
    Response.Write "ok"
    Response.End
End If
