Which of the following is the correct broadcast address for the subnet if you are examining a host with an IP address of 52.93.24.42/20 and want to determine the broadcast address for the subnet?

In binary, the address 52.93.24.42 reads like this: 00110100.01011101.00011000.00101010. The supplied subnet mask, /20, informs us that only the first 24 bits count as the network ID (which cannot change while we stay in the same subnet), and the remaining 12 bits belong to the host. 00110100.01011101.00010000.00000000 (52.93.16.0/20) is our network ID once we turn off all the host bits (after the 20th). When we enable all of the host bits, we get the following broadcast address: 00110100.01011101.00011111.11111111 (52.93.31.255/20).
