Why does the NIC allocate very few Class A addresses?
What will be an ideal response?
Class A addresses only use 8 bits for the network number and the organization is free to use the
remaining 24 bits as they wish. This uses up a large chunk of the 32-bit address space, so Class A
addresses are only assigned to very large organizations.
