<title>What is a MAC address?</title>
29
<p>A <em>MAC address</em> 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 <em>Media Access Control</em>, and each identifier is intended to be unique to a particular device.</p>
31
<p>A MAC address consists of six sets of two characters, each separated by a colon. <code>00:1B:44:11:3A:B7</code> is an example of a MAC address.</p>
33
<p>To identify the MAC address of your own network hardware:</p>
35
<item><p>Click the <gui>network menu</gui> on the menu bar.</p></item>
36
<item><p>Select <gui>Connection Information</gui>.</p></item>
37
<item><p>Your MAC address will be displayed as the <gui>Hardware Address</gui>.</p></item>
40
<p>In practice, you may need to <link xref="net-wireless-edit-connection">modify or "spoof" a MAC address</link>. 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.</p>
