What other instructional/educational topics do you think would benefit ARIN members and the user community? Please express your opinions on this mailing list, which will be summarized and presented at the CLEW working group meeting on Tuesday morning, April 3. As you formulate ideas, please review the following questions: What tutorial topics would you like to see presented at ARIN meetings? What processes or issues should be provided on cd-rom or ARIN's website? Should ARIN invite technical experts to present at ARIN meetings? Are there issues ARIN staff or members should present at other forums? Would you be interested in a one- or two-day course describing all of ARIN's registration processes? Your opinions and participation will aide ARIN in designing a program that is relevant to members and the user community. Thank you for getting involved.

I can see where an idea might start with an informal discussion on a list or at a meeting among several members with a common interest. It might even make it on as an open agenda item. But eventually, it would need to be more formally written up and discussed. Some questions that come to mind: Are there instructions on the web page now? Is there a format for proposals? What is the review process? Maybe we could look at some examples of submissions others members have made, and work on a standard format for submission. I see this as a seminar in 'How to submit a proposal to ARIN' with information on 'What is the proposal evaluation process at ARIN?' Something on the order of 1-2 hours should be sufficient I would think. Examples or case studies might be nice if they exist. They could be made up if a list of requirements existed. There are certainly lots of good topics that could evolve into a policy tweak or larger change in time.

Makes sense. I want to understand the level of formality in the process, if it exists, better than I may have in the past. Obviously I have an idea, and am exploring how I might submit that idea before going to a list with details. A question: Are draft proposals under consideration or that have been submitted to the advisory council available for viewing? It might help me to find some kindred spirits to co-present an idea, should something similar be under discussion. Based on past lurking, ideas are discussed on the appropriate list, kindred spirits (or not so kindred) relay back and forth. An item might make it onto a meeting agenda, sponsored by an advisory council member or wg/list chair? If not there is an open business/other business portion of the public meetings as I recall, where any new business can be brought up. Enough interest in an idea will generate a BOF, or meeting/seminar at a public meeting. But not until the appropriate WG has discussed it on line. Something might then be submitted to the advisory council in parallel to this process? Sound about right? I wonder if it would work best to send it to a list first, or bring it up in the open part of a public meeting to see what interest there may be. Both would be in an effort to garner support for the idea and move forward with a bonafide proposal for consideration by the advisory council. Thanks again for the input/suggestions. - Bill On Wed, 21 Mar 2001, Bill Darte wrote: > Bill, > One method to pursue which is less formal, but is appropriate and effective, > is to contact members of the advisory council.

There is no formal process our best current practice statement that I know of....but I believe that bringing the idea upon on the policy list (if it is a policy issue) now is the best way to proceed. Hopefully some discussion ensues and then the idea can be brought to the floor of policy meeting by yourself or any/all kindred spirits. You may also advocate your idea through the AC members if you choose, but we watch the policy list too. We will be able to assess the importance, interest, etc. that the membership places upon the issue. The AC will likely discuss it and may or may not then make a recommendation to the BoT.

The Board cited the need for a document outlining the policy formation process at the Fall 2000 Public Policy and Members Meeting. Last Thursday, the Board of Trustees reviewed a final draft of" ARIN Internet Resources Policy Evaluation Process", in essence a document which puts into writing the current policy creation practice. The Board approved the document, which will be published shortly on the ARIN website and handed out at the upcoming Public Policy and Members Meetings next week. I agree that this topic will make an excellent tutorial. The ARIN staff will begin development of such a program following the meeting next week. I encourage others on this list to express their opinion about this proposed tutorial, and to suggest other topics that might be of interest to the ARIN community at large.

Please take a few minutes to review it in preparation for the CLEW meeting. This document is also attached in MSWord format. Barry Skeenes Who Is ARIN? What Do They Do? What Are the Requirements that ISP Customers Must Meet? Contents 1. Introduction 2. IP Addressing Review 3. Internet Organization 4. ARIN as Custodian 5. ISPs as Agents of ARIN (LIRs) 6. Reassignment Policy 7. Early Registrations and IPv4 Address Reclamation 8. IPv6 Addressing 9. Renumbering 10. Routing Tables and Address Aggregation 11. Autonomous System (AS) Numbers 1. Introduction This document is intended to help ISPs educate their customers about ARIN's IP allocation and assignment policies and the restrictions that are required of them. All downstream customers of ISPs are equally required to follow the reassignment, justification, and utilization guidelines that their upstream ISP must follow as described in policy documents posted on ARIN's website and referenced herein. This creates a level playing field for receiving and utilizing IP numbers and helps to ensure that addresses are not wasted by providers reassigning space without restriction. IP space is a limited public resource that must be conserved and allocated prudently. 2. IP Addressing Review IP addresses are the globally unique numbers that map domain names to networks and end users. The Domain Name System (DNS) performs the translation from names to numbers. Internet Protocol version 4 (IPv4) is the IP addressing system in use today. It consists of a 32-bit string divided into four groups of eight bits (octets). Each IP address includes a network identity reference as well as a local connection identifier. In earlier times, the total available IPv4 address space, consisting of 4.29 billion addresses, was allocated following a "classful" scheme which predefined address blocks as very large (Class A), large (Class B), or small (Class C). In many cases these blocks contained many more addresses than the receiving organization could utilize. This contributed to the rapid depletion of IPv4 addresses. The success of the Internet to serve as a commercial infrastructure available to all entities required a more efficient mechanism. A new "classless" process, referred to as Classless Inter-Domain Routing (CIDR), was developed and is based on the IP numbering needs of ARIN's subscribers and end users. While not totally efficient, it utilizes addresses much more efficiently than the wasteful method of allocating predefined blocks. Understanding IP Addressing: Everything You Ever Wanted to Know, http://www.3com.com/nsc/501302.html, provides an excellent description of the IP addressing system. 3. Internet Organization The global Internet registry system in place today is hierarchical in nature and consists of the Internet Corporation for Assigned Names and Numbers (ICANN), the Address Supporting Organization (ASO) of ICANN, three Regional Internet Registries (RIRs), National Internet Registries (NIRs), Local Internet Registries (LIRs), Internet Service Providers (ISPs), and end users. ARIN's region consists of ICANN, the ASO, ARIN as the region's RIR, two NIRs, commercial ISPs, and end user organizations. ICANN maintains authority for all IP numbers globally and sets address policy with input from the ASO (an ICANN organization made up of the three RIRs), the RIRs, and the general community. ARIN receives /8 blocks from ICANN to allocate, in appropriately sized blocks, to the NIRs or qualified ISPs and end users in its region. ISPs and NIRs in turn reassign space to their downstream customers, which could be second- or third-tier providers, or end-user organizations. 4. ARIN as Custodian In the days when the Internet was expanding into a true global network, and IPv4 was getting its start, conventional thinking suggested that IPv4 would provide plenty of address space for many years to come. However, no one could foresee the rapid growth that would occur, and it soon became apparent that IPv4 resources would run out in the near term if conservation efforts were not employed. Paramount to ARIN and the work of all the RIRs, is their role in ensuring that service providers and user organizations effectively utilize address space without unnecessary waste. As of March 2001, it is estimated that nearly 60% of IPv4 space has been allocated. Estimates vary as to how long the remaining IPv4 space will last, but given the rapid development of emerging technologies and the importance of Internet resources to the world and its economy, we must all be prudent in how we handle this public resource. 5. ISPs as Agents of ARIN ARIN allocates IP addresses predominantly to large ISPs (known as ARIN subscribers), and to large end-user organizations with a user base sufficient to qualify for receiving addresses directly from ARIN. ISPs reassign numbers to other ISPs and to their end-user customers. All downstream customers are responsible for ensuring that their customers adhere to ARIN's policies. This distributes responsibility among all those involved in the allocation process and helps to ensure that the routing infrastructure remains operational. Each should effectively utilize their assigned space and that of their customers. Specifically, ISPs and all their downstream customers should employ the use of Variable Length Subnet Mask (VLSM) and CIDR. These methods provide the means for reassigning addresses in the size block needed by the respective organization or user. 6. Reassignment Policy When requesting additional allocations, ISPs must show justification for the request and must demonstrate their need by submitting reassignment information using ARIN's Shared WHOIS Project (SWIP) or a RWHOIS server. With this data in place, ARIN can readily review an ISP's address utilization to determine whether the provider satisfies the requirements. Inefficient use of IP space will hinder an organization's efforts to receive additional addresses in the future and may render it unable to meet its long-term goals and requirements. Each ARIN subscriber is responsible for ensuring that their customers provide reassignment information and identify the data by referencing the provider's Maintainer ID, an identifier assigned the provider upon their first allocation from ARIN. 7. Early Registrations and IPv4 Address Reclamation "Early registrations" refers to the large blocks of addresses that were allocated before ARIN was organized. These blocks were allocated using a classful methodology (see Section 1); and, because these blocks were often much larger than an organization needed, ARIN and the overall Internet community are now actively interested in reclaiming the early registrations that are unused or underutilized. ARIN encourages organizations to return the portions that are not being utilized, or to trade them for more appropriately sized address blocks. ARIN has been holding public discussions about this matter and seeks a satisfactory resolution for all concerned parties. This would go a long way toward meeting ARIN's mandate of ensuring equal access by all through the prudent use of all IPv4 address space. 8. IPv6 Addressing The standards community has developed a next-generation IP system which has greatly expanded the amount of address space available for the future. However, inefficient address assignments and growth of the routing tables remain serious potential threats to the scalability of the Internet, and thus its operability. Named IPv6, this system employs the use of 128-bit numbers divided into Top-Level Aggregation Identifiers (TLAs), Mid-Level Aggregation Identifiers (MLAs), and Site-Level Aggregation Identifiers (SLAs). The first TLA prefix is divided into sub-TLAs representing the initial /35 blocks that are currently being allocated. The RIRs began making IPv6 allocations in mid-1999, but it is unclear when IPv6 will become production ready. ARIN and the Internet community are proceeding in a conservative fashion to maintain routing table size and to ensure that the historical underestimation of IPv4 is not repeated with IPv6. 9. Renumbering IP addresses are allocated to ISPs in contiguous blocks, which should remain intact. Understandably, ISP customers prefer their block of IP addresses to be provider-independent (portable) in order to avoid having to renumber into a new reassignment should they change providers. However, ISPs are encouraged to require their customers to return the address space if they change ISPs. The customer would then renumber into the new provider's address space. If this practice were not followed, a situation of serious concern for the operability of the Internet today would result: routing table overload (see Section 10). 10. Routing Table and Address Aggregation Routing table entries specify how traffic is routed to individual network addresses across the Internet. IP address blocks allocated to first-tier or upstream ISPs must remain contiguous so that addresses can be aggregated. If address and route aggregation are employed efficiently, a single routing table entry is capable of representing thousands of addresses, minimizing the number of routing entries in the routing table. This is important in that too many entries would cause routing table overload, potentially rendering portions of the Internet inaccessible. 11. Autonomous System (AS) Numbers AS Numbers are globally unique numbers used to enable ASes to exchange routing information with other ASes. An AS is a connected group of IP networks that adheres to a single routing policy that differs from its border gateway peers. Requests for AS Numbers must be accompanied by verification that the requesting organization is multi-homed and its routing policy is unique. Sites that do not require a unique AS Number should use the AS Numbers reserved by the IANA (64512 through 65535) for private system use. Because AS Numbers are rapidly depleting, a new system is currently under discussion.
