Regards, Barry Skeenes ARIN Technical Writer AN OVERVIEW OF ARIN'S ROLE IN THE INTERNET INDUSTRY TODAY INTRODUCTION This document introduces who ARIN is, what ARIN does, and how the organization fits into the overall Internet industry. It is important for the community and the general populace to understand and recognize the role that ARIN, together with the other RIRs, plays in maintaining stability of the network on a global scale. The management, administrative, and technical oversight that the system of registries provides forms the infrastructure needed to help keep the Internet operational. The following paragraphs explain this in more detail. Domain Names and IP Numbers To say that IP addresses are important to running the Internet is to say that food is important for sustaining life. Simply put, without IP numbers the Internet could not function. In the form of binary code, they provide the means by which all hosts or computers connected to the network are uniquely identified. IP addresses are the numbers upon which domain names are applied. Domain names must be translated into IP numbers in order for them to be recognized by the computers, servers, networks, root zones, and routers that make up the Internet. This is accomplished through the Domain Name System (DNS), a distributed database of information used to translate domain names into IP numbers. ARIN'S HISTORY In the 1980s, the National Science Foundation's (NSF's) high-speed network, the NSFNET, was connected to the U.S. Department of Defense Advanced Research Projects Agency's (ARPA's) ARPANET, a wide area network, which essentially formed the infrastructure that we now know as the Internet. The NSF originated a project named InterNIC under a cooperative agreement with Network Solutions, Inc. (NSI) to provide registration and allocation of domain names and IP address numbers. Over time, a consensus was reached in the general Internet community to separate the management of domain names from the management of IP numbers, in part to maintain stability of the IP numbering system. As a result, ARIN was established to provide IP registration services as an independent, non-profit corporation, and opened its doors for business on December 22, 1997. ARIN'S MISSION ARIN was established for the purpose of providing administration and registration of IP numbers as a public service to the Internet community. ARIN is charged with maintaining a public trust, and, as such, allocates IP addresses in an impartial manner. Its efforts ensure that IP addresses are allocated providently as it continues to provide administration and registration services to entities in its assigned region. ARIN allocates globally unique IP addresses to ISPs for the purpose of reassigning that space to their customers, and to end users exclusively for use in their operational networks. As it distributes these IP numbers, ARIN promotes the efficient utilization of IP address space to help ensure that this valuable public resource will be available for future users. The ability for IP addresses to be routed across the network is, of course, of primary importance. Historically, the number of systems connecting to the Internet was so rapid that the ability to route data between them was in jeopardy. In fact, segments of the Internet could become inaccessible if not adequately addressed. To keep this from happening, ARIN and the other RIRs allocate IP addresses in a way that helps to control the amount of routing information distributed. ARIN TODAY ARIN is structured to respond to the requirements of the industry and its wide array of users. This structure grew out of a consensus that the administration of IP space should be managed by those who use it and depend upon it: the users at all levels, including ISPs, corporate entities, universities, and individuals. ARIN's membership is made up of representatives from these groups, which provides for a bottom-up, community-based structure that allows the organization to stay in step with the needs of the industry in an open forum. Members Meetings ARIN Members meet twice annually at various locations to accommodate members from all corners of ARIN's region. At these meetings, the members elect Board of Trustees and Advisory Council members, discuss ARIN operational and fiduciary matters, develop IP policies, and review Member services issues. Public Policy Meetings By design, ARIN is structured to provide a service to the community in an open and fair manner, and it does so through an open membership policy as well as hosting public policy meetings. The public meetings are open to all parties and individuals interested in becoming involved in discussions of IP-related issues, development of regional policies, and overall advancement of the Internet. They allow ARIN to gain a broad perspective on the issues that impact the industry the most. Working Groups ARIN promotes the formation of working groups as an extension of its public policy meetings to address important issues that require a focused group of individuals to discuss and recommend solutions to specific IP problems and issues. Funding Structure and Fees The users in ARIN's region are responsible for determining the financial structure of their registry. ARIN's funding model was established solely to recover the costs incurred in the management and administration of IP address space. The fees that ARIN charges provide the resources, including staff, equipment, and facilities, necessary to keep pace with the demands of the Internet community and are applied equitably to balance the distribution of the operating costs among those obtaining services from ARIN. Also, ARIN' s funding structure is similar to that of the RIPE and APNIC models and is based on costs experienced in prior years. SERVICES ARIN PROVIDES ARIN provides services necessary to ensure continued stability of the Internet, including the allocation of IP numbers, management of autonomous system numbers (ASNs), maintenance of inverse address mapping (in.addr.arpa), maintaining a routing registry, and help desk support, as well as providing database maintenance and verification of registrants' reassignment information. IP Allocations In allocating IP addresses, ARIN takes guidance from allocation policies and procedures developed by the Regional Internet Registries' (RIRs') members collectively, and those published by professional organizations in the industry. IP addresses are issued using either of two formats: IP version 4 (IPv4) or IPv6. Whereas IPv6 is a new method of allocation in its startup phase, IPv4 has been in use for several years. The IETF is instrumental in developing these technical standards and has an Internet Protocol Next Generation (IPNG) Working Group to develop new technology to meet future demands. Most organizations receive IP addresses from their upstream provider, i.e., those ISPs from which they obtain their Internet service. If a customer changes service providers or terminates a contract with its upstream ISP, the customer is asked to return its network addresses and must then use its new address space to renumber its network. Downstream organizations understandably prefer to permanently retain the IP addresses assigned to them by their upstream provider even when they choose to contract with another ISP. If they could take the numbers with them, they wouldn't have to renumber into new addresses. However, blocks of IP addresses allocated to any first tier or upstream ISP must remain contiguous so that addresses can be aggregated. If these blocks were to become fragmented, routing table overload could become a serious concern. ARIN and the other RIRs ensure that potential problems such as this are monitored and effectively addressed. Autonomous System Numbers (ASNs) ASNs are globally unique numbers used to identify autonomous systems, which are connected groups of IP networks that have a single and clearly defined routing policy and are used for networks to exchange exterior routing information. ARIN is responsible for assigning these numbers. Inverse Address Mapping (in-addr.arpa) Inverse address mapping is a service that provides a means for tracing data transmissions over the Internet and is designed to facilitate queries to locate gateways on a particular network. Through the use of the in-addr.arpa domain, servers that originate transmissions can be identified. Routing Registry ARIN maintains a routing registry which provides reliable routing information to organizations sending data across the Internet. It serves as a registration service whereby network operators can submit, maintain, and retrieve router configuration information. The registry serves as a repository for routing policy system information and improves customers' ability to configure and manage their networks. Help Desk Support The Registration Services Group within ARIN maintains a staff of experienced IP analysts whose responsibility is to review IP requests and to answer questions that the requesting organizations may have. ICANN Under U.S. Government contract, IANA had been responsible for the overall management of IP address space and domain names, and distributed IP address space to the RIRs for allocation to ISPs and other user organizations. The work that IANA performed has been transitioned to the newly established non-profit organization, the Internet Corporation for Assigned Names and Numbers (ICANN). The ICANN also serves as a forum for the greater user community to provide input into issues involving the Internet. Within its structure, three Supporting Organizations have been organized to form policies in their areas of expertise and to make recommendations to ICANN's Board. The Address Supporting Organization (ASO) is the body designated for making recommendations to ICANN regarding global IP address policies. While the RIRs make up the membership of the ASO, an Ad Hoc Group and an At-Large Membership provide for input from a broad spectrum of interests. REGIONAL INTERNET REGISTRIES (RIRs) The RIRs are responsible for allocating IP addresses to organizations within their assigned regions. They work together, coordinating activities to provide a seamless global network for the many varied constituencies, with their esoteric technologies, that connect to the Internet. The RIRs' role has been, and continues to be, instrumental in maintaining stability of the IP numbering system. Any organization responsible for managing a public resource must remain neutral. As such, RIRs do not show favoritism in an industry where commercial entities are highly competitive. This helps to create a level playing field by which all qualified organizations that provide Internet services have an equal opportunity to receive IP allocations within a stable fee structure. For these reasons, RIRs provide IP registration services over large geographical regions such as continents. ARIN's contribution is integral to the system of RIRs already in place. As changes to the registry system come about to keep pace with continuing changes, it is important that ARIN and the other RIRs remain at the center of the system. Through their respective members and their incumbency, they have the technical knowledge and experience in the real world to support a robust world-wide network. The RIRs consider the needs of new technology sectors and business interests in the context of the greater user base in order to provide services that are equitable for all. ROLE OF THE CONSUMER The overriding premise: IP addresses are a limited public resource that must be shared by everyone from all walks of life in all corners of the world, and by every organization large or small. The Internet may be perceived by some to be a resource that is virtually limitless and inexhaustible. Indeed, it provides access to more data than anyone ever dreamed possible. However, the Internet is constrained by the parameters of the systems on which it runs. In the world of Transmission Control Protocol/Internet Protocol (TCP/IP), the protocol in use today, this means that the pool of IP address space is finite -- a resource not without boundaries. As a public resource, IP addresses cannot be "sold" for monetary gain. Organizations cannot "buy" IP addresses, but rather are given custodianship of address blocks and are not considered to own that space. Address blocks, as well as influence in the Internet community, are too often viewed as powerful commodities to be attained. The notion of "control" over this resource is recognized as a hindrance to the future of global Internet communications. As users began connecting to the network in increasingly greater numbers, concerns arose as to whether there would be enough address space to accommodate future users. As a result, development efforts for new approaches were launched. Thus, the use and distribution of IP numbers must be a cooperative effort among all those involved. It is important that consumers distribute IP address space with forethought and under strict guidelines to ensure that the limited amount of space is used prudently and efficiently, without unnecessary waste. All ISPs from the first tier on down should require their downstream customers to follow their lead in conserving address space. End users are also charged with efficient use of their assignments. Only in this way can the Internet continue to accommodate the addition of new users connecting to it from all over the globe at an accelerated rate.

With respect to the Internet, an IP address has value only if it can be used to interconnect computers connected to the Internet. If the Internet fails to work, IP addresses have no value. There are physical and operational constraints on the IP addresses that can be used, and many of ARIN's rules reflect these realities. Think of your home telephone. It connects to the local telephone company through a pair of copper wires, bundled with other pairs into a cable containing several hundred pairs. So the telephone company knows which wire pair is associated with each physical location, the pairs are numbered. Assume your pair is number 42. The telephone company administratively assigns your telephone number, 555-1234, to pair 42. Operationally, this assignment is stored in software of the telephone switching center. If a squirrel bites through the cable, severing pair 42, your telephone service can be reassigned to pair 86. Your telephone number, however, does not need to change. In the Internet, domain names are the logical equivalent of telephone numbers. Telephone numbers and domain names both identify a certain subscriber, while wire pairs and IP addresses tell how to reach a specific location. Just as you cannot assign a 101st pair to a 100-pair cable, there are practical limitations on IP addresses. > > > > IP addresses are the numbers upon which domain names are applied.
