The company wants the IP address and MAC address of your computer. What's the use?

This is the company's network security requirements, the company must have control over the devices accessing the company's intranet, otherwise it will be unsafe. For example, some terminal equipment of unknown origin, for security reasons, network management has the obligation to shield these terminals.

Introduction to MAC address:

MAC address (English: Media Access Control Address), literally translated as media access control address, also known as LAN address, MAC address, Ethernet address or physical address, is used to confirm the location of network devices.

In the OSI model, the third network layer is responsible for IP address and the second data link layer is responsible for MAC address. The MAC address is used to uniquely identify the network card in the network. If a device has one or more network cards, each network card needs and will have a unique MAC address.
