Question

How many subnets and hosts per subnet of 172.20.0.0 255.255.255.240?

Answer 1

Answer:

Class B addresses use a default mask of 255.255.0.0

Given subnet mask = 255.255.255.240 = /28= 255. 255. 11111111. 11110000

Subnet Bits = 12 , corresponds to 2^12 = 4096 subnets

Host Bits = 4 , corresponds to (2^4-2) = 14 hosts.

4096 subnets and 14 hosts.
