This article describes in detail how to resolve IP address conflicts in wireless networks and how such conflicts are generated. I believe this article will help you.
In some wireless networks, due to the large number of clients, many administrators will use the DHCP service provided by the wireless router to provide TCP/IP
In some wireless networks, because of the large number of clients, to facilitate the management of these machines, many administrators use the DHCP service provided by the wireless router to provide clients with TCP/IP parameter configuration, such as IP address, gateway address
use is divided into four categories: 1. Reserved multicast address (224.0.0.0~224.0.0.255): These IP addresses are not assigned to specific users, and are primarily allocated to multicast routing protocols. IP packets that use this multicast address are not forwarded by the rou

We have said that the Internet is a large inter-network that connects countless networks around the world. Computers in each network are uniquely identified by their own IP addresses. Therefore, we can imagine that, on the INTERNET, each network also has its own identifier.This is very similar to the phone number in our daily life. For example, if a phone number is 0515163, the first four digits in the number indicate the region of the phone number, t
A router is a basic device in man, Wan, and Internet. It connects to a remote computer network distributed in a certain region and forwards data packets based on the layer-3 IP address of the OSI reference model. The simplicity, openness, and scalability of IP technology make it widely used in the Internet and broadban
