  <title>Mikä MAC-osoite on?</title>

  <p><em>MAC-osoite</em> on yksilöllinen koodi, jonka valmistaja on määrittänyt tietylle verkkolaitteiden ryhmälle (kuten langattomalle verkkokortille tai Ethernet-kortille). <em>MAC</em> on lyhenne sanoista <em>Media Access Control</em>, ja jokainen koodi on laitekohtainen.</p>

  <p>MAC-osoitteessa on kuusi kahden merkin sarjaa kaksoispisteellä eroteltuna (esimerkiksi <code>00:1B:44:11:3A:B7</code>).</p>

  <p>Tietokoneen MAC-osoitteen selvittäminen:</p>

  <steps>
    <item>
      <p>Avaa <gui xref="shell-introduction#activities">Toiminnot</gui>-yleisnäkymä ja ala kirjoittamaan <gui>Verkko</gui>.</p>
    </item>
    <item>
      <p>Napsauta <gui>Verkko</gui>.</p>
    </item>
    <item>
      <p>Choose which device, <gui>Wi-Fi</gui> or <gui>Wired</gui>, from
      the left pane.</p>
      <p>The MAC address for the wired device will be displayed as the
      <gui>Hardware Address</gui> on the right.</p>
      
      <p>Click the
      <media its:translate="no" type="image" src="figures/emblem-system.png"><span its:translate="yes">settings</span></media>
      button to see the MAC address for the wireless device displayed as the
      <gui>Hardware Address</gui> in the <gui>Details</gui> panel.</p>
    </item>
  </steps>

  <p>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.</p>
