Class B ip ranges from 128-191 and subnet mask is defined as 255.255.0.0
Class C ip ranges from 192-226 and subnet mask is defined as 255.255.255.0
Class D ip ranges from 227-254 and subnet mask is defined as 255.255.255.255
Class E ip addressing is Hexa decimal and is in the form of x to the power of 0,1,2,3,4,5,6,7,8,9,.........etc.
