Draft Policy 2008-3
Community Networks IPv6 Assignment

Policy Proposal 2008-3 Community Networks IPv6 Assignment

Date: 19 August 2009

Policy statement:

[Add Section 2.8 to the NRPM.]

2.8 Community Network

A community network is any network organized and operated by a volunteer group operating as or under the fiscal support of a non-profit organization or university for the purpose of providing free or low-cost connectivity to the residents of their local service area. To be treated as a community network under ARIN policy, the applicant must certify to ARIN that the community network staff is 100% volunteers.

[Modify as follows.]

b. qualify for an IPv4 assignment or allocation from ARIN under the IPv4 policy currently in effect, or demonstrate efficient utilization of all direct IPv4 assignments and allocations, each of which must be covered by any current ARIN RSA, or be a qualifying Community Network as defined in Section 2.8, with assignment criteria defined in section 6.5.9.

[Add Section 6.5.9 to the NRPM.]

6.5.9 Community Network Assignments Qualification Criteria

To qualify for a direct assignment, a community network must demonstrate it will immediately provide sustained service to at least 100 simultaneous users and must demonstrate a plan to provide sustained service to at least 200 simultaneous users within one year. For community networks located in rural regions (population less than 2,500) or in the Caribbean and North Atlantic Islands Sector, the numbers in these qualification criteria may be relaxed at ARIN’s discretion. Initial assignment size

The minimum size of the assignment is /48. Organizations requesting a larger assignment must provide documentation of the characteristics of the Community Network’s size and architecture that require the use of additional subnets. An HD-Ratio of .94 with respect to subnet utilization within the network must be met for all assignments larger than a /48. These assignments shall be made from a distinctly identified prefix and shall be made with a reservation for growth of at least a /44. This reservation may be assigned to other organizations later, at ARIN’s discretion. Subsequent assignment size

Additional assignments may be made when the need for additional subnets is justified. Justification will be determined based on a detailed plan of the network’s architecture and the .94 HD-Ratio metric. When possible, assignments will be made from an aggregatable adjacent address block.


This policy was originally proposed by community network operators to provide them with the ability to receive a direct assignment of IPv6 address resources from ARIN. The operators of such networks have expressed their need to have a stable and globally unique address assignment with which to number their network infrastructure. Many such networks are not able to meet the current criteria for a PI IPv6 assignment from ARIN. in an environment where connections to outside networks may come and go, a stable internal address structure would be very valuable. Additionally, the ability to exchange routes with others, whether locally or tunneled, and thereby have native IPv6 connectivity, would be quite beneficial. These operators were also hopeful that, once this new class of address assignments was created, they could pursue lower annual fees for community networks through the ARIN Consultation and Suggestion Process (ACSP).

There could also be a number of potential benefits to allowing community network participants to begin using IPv6 addressing. Some of these networks have many technically capable and adventurous members who would be motivated to begin developing and/or experimenting with the software extensions which will be needed to support IPv6 prefix selection among multiple IPv6 prefixes when establishing remote connections. Also, participants in networks receiving such assignments will have the necessary global-ID to experiment with the various proposals currently being developed for separating network locater from network ID.

Also, during the more than one year timeframe that this policy has been under consideration, other people have suggested other scenarios where community networks would provide a valuable resource. One such proposal was discussed at one of the Caribbean Sector meetings where some participants pointed out the efforts were being made in remote or sparsely populated areas to establish community networks which would serve as connections back to educational resources for distant learning capabilities. There are also many still wild areas of North America where such community networks could provide improved connectivity over telephone modems.

Timetable for implementation: Immediate.
