什麼是 MAC 位址？

A MAC address is the unique identifier that is assigned by the manufacturer to a piece of network hardware (like a wireless card or an ethernet card). MAC stands for Media Access Control, and each identifier is intended to be unique to a particular device.

A MAC address consists of six sets of two characters, each separated by a colon. 00:1B:44:11:3A:B7 is an example of a MAC address.

To identify the MAC address of your own network hardware:

  1. 開啟「概覽」並輸入「網路」（使用有線網路）或是「Wi-Fi」（使用無線網路）。

  2. 點一下「網路」或「Wi-Fi」以開啟該面板。

  3. 點一下網路名稱旁的 設定 按鈕。

  4. The MAC address for the device will be displayed as the Hardware Address in the Details panel.

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.
