Ip 如何将网络划分为11个子网

Ip 如何将网络划分为11个子网,ip,subnet,divide,Ip,Subnet,Divide,假设我有136.181.0.0/16,我想把它分成11个子网 我得到/19了吗?首先是/16,它只有一个子网(实际上,当子网尚未应用时,它仍然称为网络地址)。从主机位借用1位,就可以得到带有两个子网的/17。再借用一个,你会得到4个子网和前缀18。再借用一点,你就可以得到8个子网,以/19作为CIDR 不确定这里的9号、10号和11号 1st 136.181.0.0/19 2nd 136.181.32.0/19 3rd 136.181.64.0/19 4th 136.181.96.0/19

您需要11个子网,因此需要4个子网位创建16(2^4)个子网,其中有4094(2^12-2)个可用主机地址

As we require 11 subnets, we require 4 bits from the host side into the network side.

Number of bits on the network side is 20.

这不是问题。尽量不要问这样的问题。如果不是20,请尝试使用19,您只能创建8个子网。@RahulKadukar,我们至少需要11个子网,
/20
仅为您提供
8个子网
。因此,我们需要使用
/19
来获得
16个子网
,这符合11个子网的要求。136.181.0.0/19实际上是136.181.0.0到136.181.31.255,而不是你所期望的136.181.0.0到136.181.15.255。如果不是20,那么19你只能创建8个子网。@RahulKadukar,我们至少需要11个子网,而
