You have subnetted a Class A address space of 17.0.0.0 using a subnet mask of 255.248.0.0. Which of the following addresses are useable host addresses for the second subnet?

A. 17.0.8.255

B. 17.0.14.255

C. 17.0.11.255

D. 17.0.15.255

E. 17.0.19.255

A, B, and C are correct. The magic number created by the 255.248.0.0 subnet mask is 8 (in the second octet). The second subnet is 17.8.0.0, with a useable range of 17.8.0.1 to 17.15.254.

D and E are incorrect. 17.0.15.255 and 17.0.19.255 do not fall within the useable range.
