reducing the scope of the problem. But because you can customize the size of the datagram sent and the endless high-speed send, ping is also used as a tool for DDoS (denial of service attacks) by some people with ulterior motives, such as many large Web sites that have been paralyzed by hackers using hundreds of of computers with high-speed access to the Internet to send a large number of consecutive ping datagrams.
