As the network engineer, you are shown the following IP address and subnet mask: 10.100.48.27/19. What is the valid host range for this IP address?
A) 10.100.0.1 through 10.100.31.255
B) 10.100.32.1 through 10.100.63.254
C) 10.100.32.0 through 10.100.63.255
D) 10.100.32.1 through 10.100.95.255
B
Explanation: B) The correct answer is 10.100.32.1 through 10.100.63.254 because the given mask of /19 converts to 255.255.224.0, and subtracting the third value from 256 (256 - 224 ) equals 32 (magic number). The multiples of 32 include the values 32, 64, 96, and so on. Using the last two values of the IP address given, compare it to your list and take the lowest value; the subnet would be 10.100.32.0. The valid hosts range would be 10.100.32.1 through 10.100.63.254.
