Limit bandwidth (uploading/Downloading) of any device connected on LAN


Now we can limit the bandwidth (uploading/Downloading) of any device connected on LAN (Local Area Network). Using this we can target any device on network to control the speed/block the devices and for this we doesn’t need any administrator access. Earlier researcher of International Institute of Cyber Security demonstrated on how network administrator can scan whole LAN with one command.
