The subnet is 172.16.32.0, and the broadcast must be 172.16.63.25 since 64.0 is the next subnet.” The answer should state that the “the broadcast must be 172.16.63.255 since 64.0 is the next subnet.” |

On page 159, in Written Lab 3.1, number 3, we are asked to write the subnet, broadcast address and valid host range for 192.168.100.66/27. The answer on page 168 states “192.168.100.66/27. A /27 is 255.255.255.224. The fourth octet is a block size of 32. Count by 32s until you pass the host address of 66. 0, 32, 64. The host is in the 32 subnet, broadcast address of 63. Valid host range of 33-62.” The last sentence of the answer on page 168 should read: “Count by 32s until you pass the host address of 66. 0, 32, 64, 96. The host is in the 64 subnet, broadcast address of 95. Valid host range is 65-94.” |
