  <title>什么是 MAC 地址？</title>

  <p><em>MAC 地址</em>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<em>媒体访问控制（Media Access Control）</em>，每个代码对应一个唯一的设备。</p>

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

  <p>要标识网络硬件的 MAC 地址：</p>

  <steps>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Network</gui> for wired connections or <gui>Wi-Fi</gui> for
      wireless connections.</p>
    </item>
    <item>
      <p>Click on <gui>Network</gui> or <gui>Wi-Fi</gui> to open the panel.</p>
    </item>
    <item>
      <p>Click the <media its:translate="no" type="image" src="figures/emblem-system-symbolic.svg"><span its:translate="yes">settings</span></media>
      button next to the active connection.</p>
    </item>
    <item>
      <p>The MAC address for the device will be displayed as the
      <gui>Hardware Address</gui> in the <gui>Details</gui> panel.</p>
    </item>
  </steps>

  <p>实际上，您可能需要修改或“伪造” MAC 地址。例如，有些互联网服务提供商可能要求使用特定的 MAC 地址来访问他们的服务。如果网卡坏了后换用新的网卡就无法再使用他们的服务了。在这种情况下，您就需要伪造 MAC 地址。</p>
