The subnet calculator allows the use of a single subnet bit - for example, a class C address with a subnet mask of 255.255.255.128 is permitted. The subnet calculator allows a subnet ID to have its final octet equal to the final octet of its subnet mask - for example, a class C netwo...

子网划分是将一个大网络划分为多个小子网。假设你有一个Class C网络192.168.1.0/24,并希望将其划分为4个子网。 计算每个子网需要的位数: 需要划分4个子网,需要2位(2^2 = 4)。 原来的网络位是24位,加上2位子网位,共26位。 子网掩码变为255.255.255.192(前26位为1,其余为0)。
