子网区别是通过借用IP地址的若干位主机位来充任子网地址从而将原网络区别为若干子网而终结的。区别子网时,跟着子网地址借用主机位数的增多,子网的数目随之增加,而每个子网中的可用主机数逐渐削减。

(Subnet distinction is terminated by borrowing several host bits of the IP address to serve as subnet addresses, thereby distinguishing the original network into several subnets. When distinguishing subnets, the number of subnets increases with the increase in the number of hosts borrowed from subnet addresses, and the number of available hosts in each subnet gradually decreases.)
