  <title>什么是 IP 地址？</title>

  <p>IP 地址代表<em>Internet 协议地址</em>，连接到网络(如 Internet)的每个设备都有一个 IP 地址。</p>

  <p>IP 地址类似于您的电话号码，它是唯一的，这样别人就能找到您。同样，IP 地址也是惟一地标识您计算机的一组数字，这样它就可以发送和接收别的计算机数据。</p>

  <p>当前，绝大多数 IP 地址由四组数字组成，由点分开。例如 <code>192.168.1.42</code> 就是一个 IP 地址。</p>

  <note style="tip">
    <p>An IP address can either be <em>dynamic</em> or <em>static</em>. Dynamic
    IP addresses are temporarily assigned each time your computer connects to a
    network. Static IP addresses are fixed, and do not change. Dynamic IP
    addresses are more common that static addresses - static addresses are
    typically only used when there is a special need for them, such as in the
    administration of a server.</p>
