Recommended Draft Policy ARIN-2012-2
IPv6 Subsequent Allocations Utilization Requirement
Date: 26 March 2013
AC's assessment of conformance with the Principles of Internet Number
Policy 2012-2 enables fair and impartial resource administration by
creating an additional criteria under which LIRs can qualify for a
subsequent allocation. This policy does not modify the definition of who
is covered under the existing policy. This proposal addresses a
technical blindspot in the existing subsequent allocation policy that
limits initial IPv6 deployment growth. Over the last year, there has
been significant community support on the mailing list and at meetings
to rectify this blindspot. Coming to an agreement on specific wording
that does not open this to abuse has been more difficult.
The change to the NRPM is the addition of the third bullet in 6.5.3.b.
2.14. Serving Site (IPv6) When applied to IPv6 policies, the term
serving site shall mean a location where an ISP terminates or aggregates
customer connections, including, but, not limited to Points of Presence
(POPs), Datacenters, Central or Local switching office or regional or
local combinations thereof.
6.5.3. Subsequent Allocations to LIRs
a. Where possible ARIN will make subsequent allocations by expanding the
b. An LIR qualifies for a subsequent allocation if they meet any of the
* Shows utilization of 75% or more of their total address space
* Shows utilization of more than 90% of any serving site
* Has allocated more than 90% of their total address space to serving
sites, with the block size allocated to each serving site being
justified based on the criteria specified in section 6.5.2
c. If ARIN can not expand one or more existing allocations, ARIN shall
make a new allocation based on the initial allocation criteria above.
The LIR is encouraged, but not required to renumber into the new
allocation over time and return any allocations no longer in use.
d. If an LIR has already reached a /12 or more, ARIN will allocate a
single additional /12 rather than continue expanding nibble boundaries.
Subnet expansion may occur rapidly and unevenly in the early stages of
IPv6 deployment. Providers may find that they have put all of their
subnets/serving sites into service, and do not have enough space to add
an additional serving site. They may have plenty of space available
within subnets to make customer assignments, but can not turn up a new
location (eg city, pop).
