  <title>Tạo kết nối với địa chi IP cố định</title>

  <p>Most networks will automatically assign an <link xref="net-what-is-ip-address">IP address</link> and other details to your
  computer when you connect to the network. These details can change
  periodically, but you might want to have a fixed IP address for the computer
  so you always know what its address is (for example, if it is a file
  server).</p> <p>Để đặt địa chỉ IP tĩnh cho máy tính:</p>

  <steps>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Network</gui>.</p>
    </item>
    <item>
      <p>Click on <gui>Network</gui> to open the panel.</p>
    </item>
    <item>
      <p>In the left pane, select the network connection that you want to give
      a fixed address. If you plug in to the network with a cable, click
      <gui>Wired</gui>, then click the
      <media its:translate="no" type="image" src="figures/emblem-system.png"><span its:translate="yes">settings</span></media> button in the lower right corner of
      the panel. For a <gui>Wi-Fi</gui> connection, the 
      <media its:translate="no" type="image" src="figures/emblem-system.png"><span its:translate="yes">settings</span></media>
      button will be located next to the active network.</p>
    </item>
    <item>
      <p>Click on the <gui>IPv4 Settings</gui> or <gui>IPv6 Settings</gui> tab
      and change the <gui>Addresses</gui> to <em>Manual</em>.</p>
    </item>
    <item>
      <p>Enter the <em>Address</em>, <em>Netmask</em>, and <em>Gateway</em>
      information into the appropriate boxes. How you choose these will depend
      on your network setup; there are specific rules governing which IP
      addresses and netmasks are valid for a given network.</p>
    </item>
    <item>
      <p>If necessary, enter a <em>Domain Name Server</em> address into the
      <gui>DNS servers</gui> box. This is the IP address of a server which
      looks up domain names; most corporate networks and internet providers
      have dedicated DNS servers.</p>
    </item>
    <item>
      <p>Click <gui>Apply</gui>. The network connection should now have a fixed
      IP address.</p>
    </item>
  </steps>
