<title>什么是 IP 地址?</title>
<p>“IP address” stands for <em>Internet Protocol address</em>, and each
device that is connected to a network (like the internet) has one.</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>
