infection machine can not install anti-virus software or you do not know the poison. A recent example is the recent linux/xor.ddos of a fire-implanted router, whose cc control is the IP on top of AWS, because most people do not know that routers will be massively implanted with malware, and the router itself is rarely protected , it is suitable for IP to do cc, but also eliminates the complex domain name algorithm and DNS query code to ensure that the software itself is lightweight. also due to

the computer's network interface, usually the NIC . 4) The IP protocol is responsible for sending data from one computer to another on the network. The data is split into a small piece and then sent out via IP packets. Because of the complexity of the Internet link, there are often multiple lines between the two computers, so the router is responsible for deciding how to forward an IP packet. The IP packet is characterized by the number of routes sent by the block, but not guaranteed to
