# 什么是 MAC 地址？

MAC 地址是制造商为网络硬件(如无线网卡或以太网网卡)分配的唯一代码。MAC 代表媒体访问控制，每个代码对应一个唯一的设备。

MAC 地址由六组两位字符组成，由冒号分隔。比如`00:1B:44:11:3A:B7`，就是一个 MAC 地址。

要标识网络硬件的 MAC 地址：

Open the Activities overview and start typing Network.

Click on Network to open the panel.

Select Wi-Fi or Wired from the list on the left, depending on which device you want to check.

Your MAC address will be displayed as the Hardware Address on the right for a wired connection, or open the connection details by pressing on the details button to see the Details for wireless network.

In practice, you may need to modify or "spoof" a MAC address. For example, some internet service providers may require that a specific MAC address be used to access their service. If the network card stops working, and you need to swap a new card in, the service won't work anymore. In such cases, you would need to spoof the MAC address.
