    Depends on what you are trying to stop. Is the notification for a valid IP/device, that should be registering without an issue, or, is it for an IP that is attempting to "hack" your system. If it is the former, you can white-list the IP, or range, although there may be some issue, with a device, that requires "investigation". If it is the later, then you can increase the time, that the IP is blocked on each occurrence, or permanently block it for a longer time (years), if the specific IP keeps "coming back"
