Suppose that the subnet bits below for the following five subnets A-E all come from the beginning of the fourth byte of the IPv4 address; that is, these are subnets of a /24 block.

A: 00

B: 01

C: 110

D: 111

E: 1010

(a). What are the sizes of each subnet, and the corresponding decimal ranges? Count the addresses with host bits all 0s or with host bits all 1s as part of the subnet.

(b). How many IPv4 addresses in the class-C block do not belong to any of the subnets A, B, C, D and E?
