Choosing IP addresses

IP was originally developed to allow large numbers of diverse institutions to interconnect their local hosts and networks into a larger network (an Internetwork). In time, a larger entity connecting many networks and nodes evolved—the Internet. IP addresses on the Internet are administered so that the network number assigned to an institution is unique. Upon application to the Network Information Center (NIC), each institution is assigned a network number for its own use. If a network is not connected to a public network, it can use an arbitrary network number. However, the use of arbitrary numbers is
