如何將網絡劃分爲十一個子網

可以說我有136.181.0.0/16，我想將它劃分爲十一個子網如何將網絡劃分爲十一個子網

我得到了19嗎？首先它是/ 16只有1個子網（實際上當子網還沒有被應用時，它仍然被稱爲網絡地址）。從主機位中借用1位，您將得到具有兩個子網的/ 17。借用另一個，那麼你會得到4個子網和18的前綴。借用另一個位，然後你得到8個子網/ 19作爲CIDR。

不知道9日，10日和11日在這裏..

你想11個子網，所以你需要4個子網位創建16（2^4）子網，4094（2^12-2）可用的主機地址。

如果不是20，那麼只能創建8個子網。 –

@RahulKadukar，我們至少需要11個子網，'/ 20'只提供'8個子網'。所以我們需要使用'/ 19'來獲得'16個子網'，這符合11個子網的要求。 – CustomX

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.
