How many subnets and hosts per subnet can you get from the network 172.18.0.0 / 255.255.255.240

subnet : 16

host per subnet : 4094

Explanation :

172.18.0.0 is a class B type of network.

so you must take the 2 last octet in the subnet mask.

so that you change the subnet mask into the binary,

x.x.255.240 / x.x.11111111.11110000

subnets

= 2^x (x is the number of binary numbers 0)

= 2^4

= 16

hosts per subnet

= 2^y - 2 (y is the number of binary numbers 1)

= 2^12 - 2

= 4094

a few, because i should have plenty.
