Abstract SIP uses a numbering space of 64 bits, to replace the 32 bit space used in the current IP. This document specifies an administrative allocation plan wherein the numbering space is efficiently divided into continents, clusters and countries. Space is reserved for end-point identifier, metropolitan and provider assignment schemes to exist in parallel. Special consideration is given to the interaction of these schemes with the inverse function of the domain name service. Simpson expires in six months [Page i] DRAFT 64-bit allocation April 1993 1. Criteria There have been several previous plans for allocation of the 64 bit number space for future version of IP. Those plans have concentrated on one particular facet of allocation, such as ease of algorithmic transformation from older IP numbers, or simplicity of assignment. This plan is an attempt to take multiple criterion into account. This is merely a plan for allocation of the 64 bit number space in a rational fashion. It takes no position on such issues as provider versus metropolitan based aggregation, or use as end-point identifiers instead of reachability information. Instead, this plan provides the minimum level of compatibility between all such known plans, and contains features that should enhance the interworking of these different plans when simultaneously deployed. Administration The plan must account for ease of administration. In particular, the plan should allow for ease of assignment, ease of distribution of the database, and effects of deployment. The administrative organization should be the same for allocation of provider, metropolitan, and end-point identifiers. Allocation The plan must make efficient utilization of the numbering space. Each division has a potential allocation inefficiency of 1/2. Therefore, there should be as few levels of division as possible, and a firm rationale for use of each division. Access The plan must support efficient distributed access techniques. In particular, the number database should be partitioned such that access is widely distributed thoughout the network, instead of highly dependent on a few root servers. Aggregation The plan must support dense aggregation of the number space when used as provider or metropolitan based addressing. Simpson expires in six months [Page 1] DRAFT 64-bit allocation April 1993 2. Allocation Scheme Constraints Since the plan must support the IPAE compatibility mapping, only half of the numbering space is used. Of that half, only 3/4 is allocated by this plan. [Note: an earlier version of the plan used 7/8, which Steve Deering decided was too much. This version actually allocates only 21/32 of the space.] The remainder of the number space may be used as needed for uninhabited portions of the planet such as Antarctica, for other bodies within the local solar system, for intercontinental providers or organizations which refuse to interconnect within continents, clusters or countries, and for multicasting, IEEE 802 numbers, E.164 numbers, or other special uses. Countries The basic administrative unit is the country. Past experience shows that political considerations often override practical concerns in the administration of networks. This plan seeks to align the practical with the political. The country is also the basic administrative unit in the DNS. Assignment of number space along the same structure as name space should greatly ease administration. This division provides the primary intersection between metropolitan area and end-point identifier allocation. The low- numbered portions of each country are intended to be assigned according to metropolitan area. End-point identifiers should be assigned from the metropolitan areas. Small regional providers may be assigned from the high-numbered portion of each country. There are approximately 227 assigned countries and territories. This table size is 2 orders of magnitude smaller than currently handled by IP4 world-wide. An effective aggregation scheme would result from interconnection of all of the networks within each country. This may be likely in the long term (by fiat if not for practical reasons), but is not required for efficient operation of this plan. Splitting each Simpson expires in six months [Page 2] DRAFT 64-bit allocation April 1993 country into 10 disconnected portions would still be an order of magnitude smaller than currently handled by IP4 world-wide. Clusters The countries are collected into clusters. Each country is joined with other countries which are in territorial proximity, or which have a preponderance of the population within geographic proximity, or which are connected by communications installations such as undersea cables, tropospheric scattering, or shared satellite links. This division provides the primary intersection between metropolitan and provider based allocation. Approximately 1/4 to 1/2 of the numbers in each cluster are reserved for provider based allocation and future expansion. This is indicated by dashes (-) at the end of each cluster. Large regional providers should be assigned from the high-numbered portion of each cluster. New countries may be added to the low-numbered portion of each cluster. There are approximately 38 clusters. This table size is another order of magnitude smaller than the number of countries. This division is intended to aid aggregation when the number space is used for addressing and routing. It is highly likely that those providers which are not interconnected within every country will have an interconnection somewhere within the cluster. This division also improves allocation density where the cluster contains small countries or territories. More than 1/2 of a cluster is reserved for expansion in those regions which are currently volatile. Future shifts in political boundaries due to splits and joins of various countries within the cluster will have minimal impact on administration, allocation and aggregation. Continents Clusters are naturally grouped into continents, which are separated by deserts, seas, oceans, and mountain ranges. There are 9 such natural groupings defined. In the near term, it is expected that administrative assignment will be made by continental level authorities. In the long term, this assignment authority is expected to be delegated to country level authorities. Simpson expires in six months [Page 3] DRAFT 64-bit allocation April 1993 This division is intended to be used to designate points of inter-continental DNS replication, to reduce such traffic over inter-continental links. This division may also aid aggregation when the number space is used for addressing and routing. Because continental groups are joined at fewer places, this aggregation level is insensitive to changes in topology within other continents. Continental aggregation may reduce the table size by 2 orders of magnitude when compared with the number of countries. This is likely to be of most benefit for mobile systems, such as amateur radio, and in concert with a larger table of local networks. Population Population statistics and growth rates are the only useful measures generally available for estimation of the future distribution of numbers. These statistics are available from a number of sources. Unfortunately, the sources provide a wide range of estimates for current population, and an even wider range for future growth. In general, the largest such estimate was chosen to provide sufficient long term space. However, those countries which were estimated to triple the current population in 32 years were allocated only twice the space, and those which quintuple (or more) were allocated only 4 times the space. Countries experiencing rapid growth are less likely to be developing technological infrastructure in the near term. The IP4 compatibility region of the number space can be used to meet unanticipated long term needs. An estimated future population size of 8.6*10^9 needs to fit within 3/8 of 2^64 (6.9*10^18). This yields an initial estimate of 800,000,000 per person. Taking into consideration the best fit of the clusters within octet aligned available space yielded 2^48 (2.8*10^14) numbers for blocks of 400,000 population. This divides to 710,000,000 per person, which should be enough in the very long term. While at first glance this may appear to be 89% efficiency in allocation, it is noted below that the two largest countries are assigned only half their proper allocation. The actual efficiency is closer to 60%, which is still much better than the theoretical worst case of 12.5% for 3 divisions. Simpson expires in six months [Page 4] DRAFT 64-bit allocation April 1993 China and India India and China account for over half of the population of the planet. Since over half of the number space is already reserved, it proved impossible to allocate a proportionate amount to these countries. Currently, 2^59 (5.8*10^17) numbers are allocated for 1.6*10^9 persons, yielding only 360,000,000 each, which should be enough for the near term (tongue in cheek). In the future, another quarter of the number space could be allocated to these countries from the IP4 compatibility region. Small Countries and Territories Islands represent the opposite problem. Islands frequently have much fewer than 400,000 persons. Island nations and territories are often composed of many small islands. This leads to inefficiency in allocation. Therefore, small countries and islands are clustered with larger ones where possible, increasing the effective density of the space utilization. Future Expansion Someday, after the IP4 network 32-bit space has been exhausted and there is no need to globally route IP4 traffic, the 1-bit IP4 compatibility prefix may be eliminated, thus adding another 2^63 numbers (less the 2^32 permanently assigned for non-global use of IP4) to the 64-bit space. Bit and Octet Alignment To support efficient access and aggregation, this plan makes careful consideration of bit and octet alignment. Continents and most clusters are identified by the first octet, most countries, island groups and large providers by the first two octets, and all small countries and metropolitan areas within 3 octets. The DNS uses octet boundaries in the inverse lookup function. This plan provides efficient distribution of access activity world wide.
