What is the shorthand corresponding to a subnet mask of 255.255.0.0?

or

Find the CIDR value from Subnet Mask 255.255.0.0

Solution:

11111111.11111111.0.0

(2⁷ + 2⁶ + 2⁵ + 2⁴ + 2³ + 2² + 2¹ + 2⁰) . (2⁷ + 2⁶ + 2⁵ + 2⁴ + 2³ + 2² + 2¹ + 2⁰) . 0 . 0

255.255.0.0

Hence, there are 16 network bits. So the CIDR value of 255.255.0.0 is /16
