The schedule of WG meetings at RIPE 23 has been posted and the two sessions I sought for the Local IR meeting are back-to-back on Monday afternoon. A meeting of the MBONE WG parallels the second session, so I propose to use the first session (14:00 to 15:30) solely for discussion of the ripe-104++ draft circulated on Monday (copies available at ftp://ftp.ripe.net/ripe/drafts/ripe-104++.[ps|txt] ) As mentioned before, the draft is neither complete nor thoroughly checked for syntax, typos etc. Leaving those aside, the plan is to discuss only the substantive policy issues on Monday. So I've tried to summarise the changes in policy and procedure as they affect RIPE, the local IRs and the ISPs. There's repitition and omission here, but it should serve as a draft guide for the debate. Btw, page numbers refer to the PostScript version. Cheers. Mike Norris ripe-104++ - Summary of Policy Changes -------------------------------------- 1. 2.2. Goals of Public Address Space Distribution (page 4) The goals of: Uniqueness Aggregation Conservation Registration are explicitly stated. 2. 2.4 Validity of assignment (page 7) Assignments of any kind of address space are valid as long as the original criteria on which the assignment was based are still valid. 3. 3. Address Space Assignment Procedures 3.2.1 Required Information (pages 9 to 17) The following set of information must be provided with every with every request for an address assignment. 220.127.116.11. Overview of Organization Contact Persons 18.104.22.168. Current Assignment Space Usage 22.214.171.124. Request Overview Size of Request Addresses to be Used Number of Subnets Internet Connection Country Private Address Space Request Refused PI Requested 126.96.36.199. Addressing Plan 188.8.131.52. Database Information Organization Personal Data 3.2.2. Additional Information Deployment Plan Topological Map Special Circumstances Verification Information 4. 3.3. Evaluation (pages 17 to 19) Every request requires an individual evaluation process that takes current assignment guidelines into account. In the process, it is essential that IR's work to prevent the stockpiling of address space. Meanwhile, to enable proper routing, one must make strategic decisions with regard to aggregation. Evaluation Steps 1. Current address space usage 2. Network Overview 3. Private Address Space 4. Very Small Enterprises (VSE's) 5. Addressing Plan 6. Additional Information 7. Address Reservations 8. Static Dialup 9. Virtual Hosts 3.4. Assignment Procedures 3.4.1. Assignments within Allocations (page 19) Specifically, each set of address space assigned should start on a CIDR (bit) boundary. 3.4.2. PA vs PI Space (pages 20 to 22) Clear contractual arrangements which specify the duration of the address space assignment are mandatory for every assignment of PA address space. Although not strictly required, it is strongly recommended that contractual arrangements are made when assigning PI space as well. The consequences of using PA or PI space must always be made clear to the end user. Assignment of this (PA) address space is valid as long as the criteria for the original assignment are still met and only for the duration of the service agreement between yourself and ISP XXXX. Every new address space assignment must be marked as PA or PI in the RIPE database. Any assigned address space without an explicit type in the status attribute is assumed to be PI space. Formally, address space is not of type PA unless there are contractual agreements regarding the assignment's termination. It is therefore recommended that IRs ask end users to release non-PA address space upon termination of service. 3.5. Assignment Window (page 24) The assignment window is the maximum number of addresses that can be assigned by the local IR to an end user without prior approval by the RIPE NCC. Currently, the maximum size of the assignment window for any local IR is 4096 addresses (/20). If such errors are noticed by the RIPE NCC, the assignment window for the local IR may be decreased to prevent the staff from making erroneous assignments involving a substantial amount of address space. 4. Rules and Guidelines for Allocations (page 26) If a local IR allows another IP service provider to make an assignment from its allocated address space, the local IR is still responsible to guarantee the assignment is made according to the guidelines specified in this document. 4.1. Slow Start of Allocations (page 26) The minimum allocation is /19 (8192 addresses). The maximum size of an individual allocation is /16 (65536 addresses). The size of allocations is based solely on the rate that previously allocated address space has been assigned to end users. 4.2. First Allocation (page 27) The first allocation will be made automatically by the RIPE NCC, generally upon receipt of the first assignment request from the local IR. Because there is no information about the rate at which a new IR will make address assignments, the size of the first allocation is always set at the minimum. 4.3. Further Allocations (page 27) Additional address space will be allocated after the information delivered with the request has been verified, and a new allocation has been deemed necessary. While the RIPE NCC always aims to further the aggregation goal, and therefore to allocate contiguous space, the RIPE policy is that under no circumstances are multiple allocations made to the same local IR guaranteed to be contiguous. 4.4. Allocation Registration (page 28) ALLOCATED UNSPECIFIED This address space has been allocated to an IR, and assignments made from it may be either provider aggregatable or provider independent. This type of allocation is obsolete, and will not be applied to future allocations. Some older allocations have been used for both PA and PI assignments, and as such receive this allocation type.
