IP address conflicts are generally due to manual setting of IP. Generally speaking, there are two possibilities:

Both computer An and computer B have the same IP address manually.

Computer An acquires it automatically, and computer B manually sets the same IP address as computer A.

When an IP address conflict occurs, you can see the MAC address of the conflicting party through the arp-a command. As shown below:

You can find the conflicting computer according to this MAC address, and then deal with it later. My friends want to say that it's too troublesome to find it like this every time. So how can the local area network find IP address conflicts to be eliminated?

First of all, it is necessary to obtain the IP automatically.

When IP is obtained automatically, all IP addresses are assigned uniformly by the DHCP service, so that there is no IP address conflict.
