Class-full IP Addresses

Class-full IP Addresses IP addresses are divided into classes A, B, C, D and E. Classes A, B and C are used for addressing end devices like computers, printers, routers etc. Class D addresses are used for multicast and Class E addresses are reserved for experimental purposes. Class A Addresses
