A supernet has a first address of 205.16.32.0 and a supernet mask of 255.255.248.0. A router receives four packets with the following destination addresses. Which packet belongs to this supernet?
Answer: Option 4Explanation:Given first address: 205.16.32.0 Supernet mask: 255.255.248.0Option 1: 205.16.42.56performing bitwise and operation with supernet mask11001101.00010000.00101010.0011100011111111 .11111111 . 11111000 .00000000-----------------------------------------------------------11001101.00010000.00101000. 00000000? 205.16.40.0 ? 205.16.32.0 Hence this is not the correct Option.Option 2: 205.17.32.76performing bitwise and operation with supernet mask11001101.00010001.00100000.0100110011111111 .11111111 . 11111000 .00000000-----------------------------------------------------------11001101.00010001.00100000. 00000000? 205.17.32.0 ? 205.16.32.0Hence this is not the correct Option.Option 3: 205.16.31.10performing bitwise and operation with supernet mask11001101.00010000.00011111.0000101011111111 .11111111 . 11111000 .00000000-----------------------------------------------------------11001101.00010000.00011000. 00000000? 205.16.24.0 ? 205.16.32.0Hence this is not the correct Option.Option 4: 205.16.39.44performing bitwise and operation with supernet mask11001101.00010000.00100111.0010110011111111 .11111111 . 11111000 .00000000-----------------------------------------------------------11001101.00010000.00010000. 00000000? 205.16.32.0 == 205.16.32.0Hence this is the correct Option.
