基于类的 IP 地址在实际应用中出现的问题及解决方案通过指定网络标志和主机标志,IP 地址形成了一个等级结构的地址空间,便于组织和管理,但是随着 Internet 上主机数量的快速增长,出现了以下几个主要的问题:1、僵化的地址分配方案使很多地址被浪费在许多情况下,不需要某类 IP 地址下的全部主机地址空间,例如,某个网络共有30台主机,即使被赋予一个最小的 C类网络.也将浪费224个 IP 地址。解决的方法是,增加 TCP/IP 地址的层次结构,添加一个
Based on the IP address in the class of problems and solutions in practice By specifying the network logo and host logo, IP address formed a hierarchical address space for easy organization and management, but with the rapid growth in the number of hosts on the Internet, The following major issues have emerged: 1. Foolish address allocation schemes waste many addresses. In many cases, it does not require all of the host address space for a type of IP address. For example, if a network has a total of 30 hosts, Is given a minimal Class C network and will also waste 224 IP addresses. The solution is to add a hierarchy of TCP / IP addresses and add one
