Lab 3.1, #3

Write the subnet, broadcast address, and valid host range

3. 192.168.100.66/27

Answer in text (page 168):
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

My answer:
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, 96. The host is in the 64 subnet, broadcast address of 95. Valid host range of 65-94.
