Best answer
Correct Answer - Option 3 : Wasted

The correct answer is option 3

In classful addressing, once a network id is assigned to an organization, there is no method available to allocate the unused IP addresses of that network to other organizations. Hence a large part of the available addresses is wasted.

To overcome this wastage CIDR blocking scheme is developed.

In this scheme, a network can be formed in chunks of IP addresses required and can be used by different organizations.

Subnets can also be formed within the network block.
