IPV4地址如何分类,分类解决了什么问题?
IPV4地址分类主要有A,B,C,D和E五类。
A类地址用于大型网络,这类地址拥有最高级别的网络号,可分配给大型网络,可以拥有超过65,000台主机。
B类地址用于中型网络,这类地址拥有中等级别的网络号,可分配给中型网络,可以拥有超过256台主机。
C类地址用于小型网络,这类地址拥有最低级别的网络号,可分配给小型网络,可以拥有超过256台主机。
D类地址用于多播,这类地址用于组播,可以实现一对多或多对多的数据传输。
E类地址保留给研究用,目前还没有使用。
IPV4地址的分类可以将地址空间有效的分配给不同大小的网络,同时可以解决分配IP地址资源的问题,让每个网络都能获得足够的IP地址。
