200.195.55.64/29

network address : 200.195.55.64
subnet mask     : 255.255.255.248

A = net address in binary     : 11001000.11000011.00110111.01000000
B = subnet mask in binary     : 11111111.11111111.11111111.11111000
C = complement of subnet mask : 00000000.00000000.00000000.00000111

broadcast address = A || C    : 11001000.11000011.00110111.01000111

 ==> 200.195.55.71
