F I G U R E   2 7 .   H o s t   A d d re s s e s   f o r   S u b n e t   # 1 4   1 4   2
( 1 4 0 . 2 5 . 2 3 8 . 6 4 / 2 7 )
Each of the subnets of Subnet #14 14 has 5 bits in the host number
field. This means that each subnet represents a block of 30 valid host
addresses (25  2). The hosts will be numbered 1 through 30. 
The valid host addresses for Subnet #14 14 2 are listed in the following
sample code. The underlined portion of each address identifies the
extended network prefix, while the bold digits identify the 5 bit host
number field: 
Subnet#14 14 2: 10001100.00011001.11101110.010 00000 = 140.25.238.64/27
Host #1 10001100.00011001.11101110.010 00001 = 140.25.238.65/27
Host #2 10001100.00011001.11101110.010 00010 = 140.25.238.66/27
Host #3 10001100.00011001.11101110.010 00011 = 140.25.238.67/27
Host #4 10001100.00011001.11101110.010 00100 = 140.25.238.68/27
Host #5 10001100.00011001.11101110.010 00101 = 140.25.238.69/27

Host #29 10001100.00011001.11101110.010 11101 = 140.25.238.93/27
Host #30 10001100.00011001.11101110.010 11110 = 140.25.238.94/27 
The broadcast address for Subnet #14 14 2 is the all 1s host address or: 
10001100.00011001.11011100.010 11111 = 140.25.238.95
The broadcast address for Subnet #6 14 2 is exactly one less than the
