分类网络 Classful network
（重定向自Class C network）
分类网络（Classful Addressing）或称「分级式寻址」，是在1993年左右用于描述互联网的网络体系的一个术语。它将IPv4的IP地址分成五个类别。每个类别的地址都由它们的前3位来标识；每个类别都定义了网络的大小或者类型（单播或多播）。
现在，只有在一些网络软件和硬件组件的默认参数值（如子网络遮罩），才依然使用分类网络这个概念；但是这个术语在网络管理员间的讨论中还经常可以听到。

A classful network is a network addressing architecture used in the Internet from 1981 until the introduction of Classless Inter-Domain Routing in 1993. The method divides the address space for Internet Protocol Version 4 (IPv4) into five address classes. Each class, coded in the first four bits of the address, defines either a different network size, i.e. number of hosts for unicast addresses (classes A, B, C), or a multicast network (class D). The fifth class (E) address range is reserved for future or experimental purposes.
