following sample code. The underlined portion of each address identi 

fies the extended network prefix, while the bold digits identify the 5 

bit host number field:

Defining the Broadcast Address for Each Subnet

The broadcast address for Subnet #2 is the all 1s host address or: 

11000001.00000001.00000001.010 11111 = 193.1.1.95 

Note that the broadcast address for Subnet #2 is exactly one less than

the base address for Subnet #3 (193.1.1.96). This is always the case the

broadcast address for Subnet #n is one less than the base address for

Subnet #(n+1).
