Policy Proposal 2007-20
Definition of known ISP and changes to IPv6 initial allocation criteria

Author: Kevin Loch

Proposal type: new

Policy term: permanent

Policy statement:

Add the following section 6.2.10:

6.2.10 Existing ISP

An existing ISP is an organization which meets the following criteria:

1. Has IPv4 or IPv6 address space directly allocated by ARIN; or
2. Has at least a total of an IPv4 /23 or an IPv6 /44 of address space reallocated to them via SWIP by one or more upstream ISPs.

Address space directly assigned from ARIN or reassigned from upstream ISPs does not count towards these requirements.

Replace (d) with the following text:

d. be an existing ISP in the ARIN region or have a plan for making assignments to at least 200 separate organizations within five years.


This policy proposal would change two things in the IPv6 Initial allocation criteria. It adds a definition for "known ISP" and changes "200 /48 assignments" to 200 assignments of any size, but to separate organizations.

Existing ISP:

The term "existing, known ISP" in the IPv6 ISP qualification section is too vague and does not give ARIN staff sufficient guidance for evaluating qualifications. This text defines "existing, ISP" in a precise manner and removes the unnecessary and ambiguous word "known".

It has come to the author's attention that several organizations have been refused IPv6 ISP allocations because they were not considered an existing, known ISP. At least one of these organizations has a /18 worth of IPv4 space reallocated to them by various upstream ISPs and over 200 IPv4 customers. An organization's choice to use provider addresses does not have any affect on whether or not they are in fact an ISP.

Address space that has been reallocated (not reassigned) is a good indicato of an ISP as those SWIP templates are only supposed to be used for downstream ISPs.

The IPv4 /23 value was selected to match the utilization requirement for the smallest direct IPv4 allocation from ARIN under current policy.

The IPv6 /44 value was selected to represent a number of downstream customers comparable to the IPv4 requirements.

Updates to IPv6 initial allocation criteria:

Section recommends /56 assignments in some cases and /48 assignments in others. The Initial allocation criteria should reflect the flexibility of these recommendations. An ISP should not have to provide an inefficient address plan on their application even though they expect to have over 200 IPv6 customers.

Timetable for implementation: Immediate
