1. Convert the following prefix subnet masks to the corresponding decimal subnet mask. Remember that the prefix shorthand notation represents how many binary 1s are in the subnet mask.

Example: /24 = 255.255.255.0

a. /16

b. /30

c. /28

d. /20

e. /23

B. Convert the following decimal subnet masks to the prefix format :

a. 255.0.0.0

b. 255.255.248.0

c. 255.255.255.192

d. 255.255.255.128

e. 255.255.254.0
