Pretend we are defining a new class of networks: 1 byte for network IDs and 1 byte for hostID. The definition of class A is:

networkdID is : 0xxx- and the one byte hostID cannot contain all 0s and 1s.

The definition of class B is:

networkdID is : 10xx- and the one byte hostID cannot contain all 0s and 1s

The definition of class C is:

networkdID is : 110x- and the one byte hostID cannot contain all 0s and 1s.

How many total IP addresses can we have with the above definition.
