Policy Proposal Name: PI assignments for V6

Author: Owen DeLong

Policy term: permanent

Policy statement:

Any end-site or other organization which meets the current tests for
assignment of an autonomous system number (ASN) shall also qualify for one
IPv6 prefix assignment or allocation of the minimum size justified by them
under the ARIN guidelines for LIR assignment to such an organization.  If
the organization wishes to receive an allocation, they must meet the tests
for being an LIR, except that this smaller allocation will not require a
plan for assigning to an additional 200 organizations.  To qualify as an
LIR under this policy, the organization must have the intent of assigning
to additional organizations, and, should be able to show ARIN reasonable
evidence of such intent.

If the organization grows to require more space, they will not be entitled
to an additional block, but, may obtain a new replacement block of
sufficient size to meet their needs in exchange for agreement that their
existing block will be reclaimed and may be reissued to a different
organization in 24 months.


There is a legitimate and growing need for provider independent addressing
for end-site organizations and small ISPs.  While there were and are
technical reasons for limiting this in the v4 world, they need to be
solved in the v6 world, or, we will not see widespread adoption of v6.

This policy does not promote extreme growth in the routing table, as it
would provide support for fewer than 70,000 v6 prefixes if every
organization that currently has an ASN were to get an assignment, grow,
and, be in the 24 month renumbering period.  Realistically, it is
unreasonable to think that this policy would contribute even 10,000 routes
to the v6 table in the near term future.

This policy provides for reasonable v6 provider independent assignments
and allocations without creating a land-grab, explosive routing table
growth, or a v6 swamp.

All such assignments under this policy shall be subject to the same
renewal criteria as v4 end-user assignments with a fee structure to be set
by ARIN in the usual and customary way.

Timetable for implementation:

Upon adoption by the ARIN board of trustees.
