.... Even the gradual depletion of the IPv4 address space has been slowed by a new approach to assigning network addresses which assigns consecutive class C addresses to large corporations rather than a single class B address (which can consume as many 11 IPv4 host addresses as 256 class C networks) FLYV92] The use of subnetworking to further divide the class B network addresses that are issued [MP85] has also helped to extend IPv4 s effective lifespan. However, it is inevitable that the IPv4 address space will be depleted soon, and this is the driving force behind development of a new Internet ....

....network. There were too few class B networks and assigning several class C network addresses to each organization would inflate the backbone network routing tables beyond their current size of approximately 50,000. Thus, the current Internet has transitioned to Classless Interdomain Routing (CIDR) [16], where address ranges carry explicit prefix lengths designating the routing relevant part of the address. A class C address in the old, so called classfull scheme is equivalent to a 24 address since 24 bits are used for routing. 5 The multicast address space, the class D addresses shown in ....

....are driving this: routing and addressing. Global internet routing based on the on 32 bit addresses of IPv4 is becoming increasingly strained. IPv4 address do not provide enough flexibility to construct efficient hierarchies which can be aggregated. The deployment of Classless Inter Domain Routing [2] is extending the life time of IPv4 routing by a number of years, the effort to manage the routing will continue to increase. Even if the IPv4 routing can be scaled to support a full IPv4 Internet, the Internet will eventually run out of network numbers. There is no question that an IPng is ....

....1366 did not, however, discuss nor specify the more complex and far reaching effect of how IP registries would manage the sub allocations of these newly defined large geographic blocks. Sub allocation or down stream IP address space provisioning remained, for the most part, unspecified. RFC 1338 [21] on IP address supernetting, was published in June 1992 prior to the July IETF BOF, with the recommendation: The NIC should begin to hand out large blocks of class C addresses to network service providers. Service providers will further allocate power oftwo blocks of class C addresses ....

....July IETF BOF, with the recommendation: The NIC should begin to hand out large blocks of class C addresses to network service providers. Service providers will further allocate power oftwo blocks of class C addresses from their address space to their subscribers. RFC 1338, June 1992 [21] RFC 1338 was a major paradigm shift to establish a provider based addressing routing hierarchy that was multitiered on binary boundaries. This would become relevant in RFC 1366, not as provider based addresses hierarchy, but as a geographical hierarchy. Kleinrock and Kamoun [22] 2] demonstrated ....
