建立大型企业Intranet的人们都知道,A类IP网络地址可以支持1600万台主机和数千个子网络,如果InterNIC能够放弃其中的一个,事情就会简单许多。此外,只有将特殊A类地址空间——网络10.0.0.0——再分割成子网,创建巨型企业Intranet。这样不仅可保护企业信息资产,还可访问Internet和地址管理的灵活性和安全性。这些特殊的IP地址被Internet的RFC(Request for Comment)指定作为专用网络 People who build large enterprise intranets know that Class A IP network addresses can support 16 million hosts and thousands of subnetworks and that it would be much easier if InterNIC was able to drop one of them. In addition, only a special Class A address space - network 10.0.0.0 - subdivided into subnets, create a giant corporate intranet. This not only protects enterprise information assets but also the flexibility and security of Internet and address management. These special IP addresses are specified by the Internet’s Request for Comment (RFC) as a private network
