CIDR在路由表中增加了子网掩码(subnet masking),从而可以更细分网络。利用CIDR,我们可以灵活的将某个范围的IP地址分配给某个网络。 1) IP地址分类 在IP接力赛中,我提到,IP地址可以分为如下几类: IP class From To Subnet Mask A 1.0.0.0 126.255.255.255 255.0.0.0 B 128.0.0.0 191.255.255.255 255.255.0.0 ...
def subnetMaskToCIDR(subnetMask: String): String = { val binaryMask = subnetMask.split("\\.").map(Integer.toBinaryString(_)).mkString(".") val cidr = binaryMask.count(_ == '1') s"/$cidr" } // 示例 val subnetMask = "255.255.255.0" val cidr = subnetMaskToCIDR(subnetMask) pri...

VLSM(Variable Length Subnet Mask——可变长子网掩码) 这种策略只能在所用的路由协议都支持的情况才能使用,例如开放式最短路径优先路由选择协议(OSPF)和高级距离矢量路由选择协议(EIGRP).RIP版本1由于出现早于VLSM而无法支持.RIP版本2则可以支持VLSM. VLSM允许一个组织在同一个网络地址空间中使用多个子网掩码.利用VLS...

pfSense® software uses CIDR (Classless Inter-Domain Routing) notation rather than the common subnet mask 255.x.x.x when configuring addresses and networks. Refer to the CIDR Subnet Table to find the CIDR equivalent of a decimal subnet mask.CIDR...
Classless Inter-Domain Routing is based on variable-length subnet masking (VLSM), which is an efficient way of subnetting real networks. This concept allows all subnet masks to have varying sizes, according to the user's requirement. Asubnet masksplits an IP address of a device into a host...
