Which of the following IP addresses fall into the CIDR block of 110.68.4.0/18 ? (Choose three)

A: 110.68.8.32
B: 110.68.7.64
C: 110.67.6.255
D: 110.66.3.254
E: 110.65.5.128
F: 110.64.12.128

The answer is "B, C, E"


But doesn't 110.68.4.0/18 equal an address range from 110.68.0.1 -> 110.68.63.255 ?
Which eliminates C,D,E,F...
