If it is a small unit, there are fewer computers. All computer network managers in the unit have the right to check, find him and hey. If the company has more than 100 computers, you can take this opportunity to control the domain, so that you are king on the company network and everyone listens to you.

In addition, if the company has a three-layer switch and a two-layer access switch for WEB network management, it is no problem to find him directly according to the access port corresponding to the MAC.

I am deeply convinced that it is generally deployed at the company's network exit, and Ben is still making trouble in this MAC intranet. Besides, it is not easy to find him by changing the MAC address with software.
