We know that for the use of TCP/IP protocol on Internet and Intranet networks, each host must have an independent IP address, and only hosts with IP addresses can communicate with other hosts on the network. With the vigorous promotion of network applications and the rapid increase in network clients, problems caused by static IP address allocation, such as IP address conflicts, have emerged one after another. IP address conflicts have serious impacts; first, network clients cannot work properly. As long as there is a conflicting machine on the network and it is powered on, frequent notifications of address conflicts will appear on the client: "If the security strategy of a certain application on the network (such as access permissions, access control, etc.) is based on IP addresses, these unauthorized IP users can pose a serious threat to the security of the application system."
