D) The correct answer is 10.10.110.1 through 10.10.110.62 because, with the given mask of 255.255.255.192, subtracting the fourth value from 256 (256 - 192) equals 64 (magic number). The multiples of 64 include the values 0, 64, 128, and 192. Using the last value of the IP address given, compare it to your list and take the lowest value; the subnet would be 10.10.110.0. The valid hosts range would be 10.10.110.1 through 10.10.110.62.
