What is the mac address of the CVM? The MAC address of the server, which is the media access control address, also known as the local area network address (LAN Address), Ethernet address, or physical address, which is an address used to confirm the location of devices on the network.

The MAC address is represented in hexadecimal numbers, with a total of six bytes (48 bits). Among them, the first three bytes are the codes assigned by IEEE's registration authority RA to different manufacturers (high 24 bits), also known as "compiling unique identifiers", and the last three bytes (low 24 bits) are assigned to the production adapter interface by each manufacturer, called extension identifiers (uniqueness).

MAC address is used to uniquely mark a 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. The mac address of the CVM can be modified. If you have multiple network cards, you can only modify the MAC address of the primary network card.

How to check the mac address of elastic CVM
