<p>在Internet协议开发的早期阶段，网络号始终是最高阶的八位元组（最高且有效的八位）。由于此方法仅允许256个网络使用，因此很快被证明这样是不够的，因为所开发的其他网络都独立于已经由网络号指定的现有网络。1981年，随着<a href="/wiki/%E5%88%86%E7%B1%BB%E7%BD%91%E7%BB%9C"

title="單播">单播</a>寻址定义了三个类别（A类、B类和C类）。根据派生的类，网络标识基于整个地址的八位字节边界段。每个类别在网络标识符中依次使用其他八位元组，从而减少高阶类别（B类和C类）中的主机数量。上表概述了这个过时的系统。 </p><p>分类网络的设计在Internet启用阶段就达到了这个目的，但是对于20世纪90年代的网络的迅速发展，它缺乏可扩展性。地址空间的类系统在1993年被<a href="/wiki/%E6%97%A0%E7%B1%BB%E5%88%AB%E5%9F%9F%E9%97%B4%E8%B7%AF%E7%94%B1" title="无类别域间路由">无类别域间路由</a>（<a

</p><p>IP中可能的地址有2<sup>128</sup>≈3.4×10<sup>38</sup>个，具体数量为340,282,366,920,938,463,463,374,607,431,768,211,456（即16<sup>32</sup>)，因为32位地址每位可以取16个不同的值。在很多场合，IP地址由两个逻辑部分组成：一个64位的网络前缀和一个64位的主机地址，主机地址通常根据物理地址自动生成，叫做EUI-64（或者64-位扩展唯一标识）。

<p>就像IPv4为专用的网络保留的地址一样，在IPv6中也有被预留的地址。在IPv6中，这些地址被称为唯一本地地址（ULA）。路由前缀：<i>fc00::/7</i> 就是为这个块保留的，且被分为2个 <i>/8</i> 块，都具有不同的隐藏策略。这些地址包括一个40位的伪随机数，如果站点合并或者数据包被错误的路由，则可以将地址冲突的风险降到最低。

<p>IP地址是在主机加入网络时动态分配的，或是通过主机硬件/软件的配置永久分配给主机的。永久性的配置也称为使用<b>静态IP地址</b>。相反，在每次重新启动时分配的IP地址，称为使用<b>动态IP地址。</b> </p><p>动态IP地址是通过网络使用<a

title="动态主机设置协议">动态主机配置协议（DHCP）</a>分配的。DHCP是分配地址最常用的技术。它避免了为网络上的每台设备分配特定静态地址的管理负担。如果某些设备在特定的时间处于联机状态，它还允许设备共享网络上有限的地址空间。通常，在现代的台式计算机操作系统中，默认情况下会启用动态IP地址分配。 </p><p>DHCP分配的地址于租约相关联，并且一般都是具有有效期。如果主机在到期前未能续订租约，则可以将该地址分配给其他设备中的一台设备。某些DHCP实现会在主机每次加入网络时根据其<a href="/wiki/MAC%E5%9C%B0%E5%9D%80" title="MAC地址">MAC地址</a>尝试将相同的IP地址重新分配给该主机。网络管理员可以通过基于MAC地址分配特定的IP地址来配置DHCP。 </p><p>DHCP并不是唯一一种动态IP地址分配技术。Bootstrap协议是DHCP的类似协议和前身。拨号和某些宽带网络使用<a
