IP地址子网划分原理及应用

The Principle and Application of IP Address Sub-netting

随着IP地址日益缺乏,如何有效合理地使用有限的IP地址是网络应用中首先要解决的问题。在IP地址的规划中,需要高效合理地进行IP地址的分配,既要符合预期要求,又不能造成IP地址的浪费。利用可变子网掩码和无类别域间路由两项技术可以很好地解决IP地址分配问题。

With growing shortage of IP address,how to effectively and rationally use limited IP address is the first problem to be solved in network application.In the IP address planning,it is necessary to meet the expected demand and avoid waste of IP addresses.We can solve the practical problems of the IP addresses planning by using Variable Length Subnet Mask and Classless Inter-Domain Routing.
