1) Classful Addressing IPv4 addressingused the concept of classes. This architecture is known asclassful addressing. In the classful addressing, there are 5 classes in which the address space is divided:A, B, C, D, and E. Each class occupies some fraction of the address space. ...
Classless addressing is an IPv4 addressing architecture that uses variable-length subnet masking. The solution would come in 1993, as Classless Inter-Domain Routing (CIDR) introduced the concept of classless addressing. You see, with classful addressing, the size of networks is fixed. Each address ...

Note the classful addressing scheme is rather historic. I bet you will never see network with classful addressing scheme used.It's about fifteen years since I've seen this kind of thing for the last time I see no error. IP and explicit mask is common to both method.Classfullhave class (...
An organization or service provider managing addressing for a large number of hosts or networks should use supernetting -- possibly in combination withnetwork address translation-- to partition out IPv4 and IPv6 addresses and to optimize traffic efficiency. ...
