  <title>创建一个固定 IP 地址的连接</title>

  <p>当您连接到网络时，多数网络会自动为您的计算机分配 I P 地址和其他信息。这些信息可能会定期更改，但您可能要为计算机设置固定的 IP 地址，以便时刻了解您计算机的 IP 地址(例如当该计算机被用于文件服务器时)。</p>

  <steps>
    <title>要为计算机提供固定(静态)IP 地址：</title>
    <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 have
      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 <gui>IPv4</gui> or <gui>IPv6</gui> in the left pane
      and change the <gui>Addresses</gui> to <em>Manual</em>.</p>
    </item>
    <item>
      <p>Type in the <gui xref="net-what-is-ip-address">IP Address</gui> and
      <gui>Gateway</gui>, as well as the appropriate <gui>Netmask</gui>.</p>
    </item>
    <item>
      <p>In the <gui>DNS</gui> section, switch <gui>Automatic</gui> to
      <gui>OFF</gui>. Enter the IP address of a DNS server you want to use.
      Enter additional DNS server addresses using the <gui>+</gui> button.</p>
    </item>
    <item>
      <p>In the <gui>Routes</gui> section, switch <gui>Automatic</gui> to
      <gui>OFF</gui>. Enter the <gui>Address</gui>, <gui>Netmask</gui>,
      <gui>Gateway</gui> and <gui>Metric</gui> for a route you want to use.
      Enter additional routes using the <gui>+</gui> button.</p>
    </item>
    <item>
      <p>Click <gui>Apply</gui>. The network connection should now have a fixed
      IP address.</p>
    </item>
  </steps>
