Classful Addressing vs Classless Addressing

Hello Friends, In this blog post I am going to let you know about the differences between classful addressing and classless addressing.

In classful addressing, the concept of classes was used to designate the different type of addressing, whereas in classless addressing there are no classes, but the address is still granted in blocks.

In classful addressing, address space is divided into five classes namely, class A, B, C, D, and E. Each class occupies some part of the address space. Whereas in classless addressing it incorporates variable-length blocks of IP addresses that essentially belong to no class.

In classful addressing a large part of the available addresses was wasted, whereas in classless addressing which is almost obsolete is replaced with classless addressing.
