The Internet protocols policies are now documented in technical reports called Request For Comments (RFCs). The Internet Protocol is addressed in RFC ... bits are the network ID, and the remaining 24 bits are the host ID. The maximum number of networks is 27, and the maximum number of hosts is 224.
