Hello All,
There has been an update to the text of ARIN2014-16: Section 4.10
Austerity Policy Update. Based upon previous feedback and suggestions
there has been substantial changes to the original text. This new text
is
included below and will be discussed at the upcoming meeting in
Baltimore.
. . .
Updated Text
==============================
Policy statement:
Replace Section 4.10 with the following policy.
4.10 Dedicated IPv4 block to facilitate IPv6 Deployment
When ARIN receives its last /8 IPv4 allocation from IANA, a contiguous
/10
IPv4 block will be set aside and dedicated to facilitate IPv6
deployment
and continued transition from IPv4 to IPv6.
Since this event is now in the past, it might make more sense for the
update to say "When ARIN received its last... block was set aside and
dedicated... "
That seems like a fine editorial change. This text is just from the
current policy.
Address space received from IANA under the “Global Policy for Post
Exhaustion IPv4 Allocation Mechanisms by the IANA (NRPM 10.5)” by ARIN
shall be allocated or assigned under this section.
Allocations and assignments from this block must be justified by
immediate
IPv6 deployment requirements. ARIN shall use sparse allocation within
these blocks.
4.10.1 Austerity Policy
Organizations must obtain an IPv6 block to receive a block under
section
4.10.1 and show documentation on how the IPv6 and IPv4 block will be
used
to facilitate an organization¹s operational needs. These allocations
or
assignments will be subject to a minimum size of /28 and a maximum
size of
/22.
In order to receive an allocation or assignment under this policy:
1. the organization, its parent(s), or subsidiary organizations, may
not
have received IPv4 address resources greater than or equal to a /22
from
ARIN or any other RIR;
2. the organization must show immediate use (within 90 days) of 25% of
the
allocation;
It feels like the numbered sections should end here, because the next
two are not requirements for receiving a block under this policy,
rather statements of what will happen next. But that's minor.
3. the organization is eligible to receive only one contiguous IPv4
block
under this section;
By extension, does that mean the organization, its parent(s) or
subsidiaries?
Yes, the intention is that only one of these blocks is available to an
organization, its parent(s) or subsidiaries.
4. the organization may apply to ARIN for an increase in their
allocation
up to a /22, if the previous allocation under this section shows a
utilization of at least 80%, increases will only be granted if
adjacent
bit-boundary aligned space is available at the time of request.
Does 'utilization' in this sense mean 'active v4 addresses', or
'active v4 addresses being used in accordance with the documentation
provided to justify the original allocation'? Bullet 2 in the existing
4.10/new 4.10.2 seems to cover this but only for that section.
My intention is that if/when the organization comes back to ARIN to grow
their prefix that they are actively using 80% of the block which was
allocated under 4.10.1. So if you have a /24 from 4.10.1 and you are
using ~205 IP addresses you can expand to the next bit boundary.
4.10.2 Transition technologies
Allocations and assignments from this block must be justified by
immediate
IPv6 deployment requirements. Examples of such needs include: IPv4
addresses for key dual stack DNS servers, and NAT-PT or NAT464
translators. ARIN staff will use their discretion when evaluating
justifications.
These allocations or assignments will be subject to a minimum size of
/28
and a maximum size of /24. ARIN shall reserve a minimum of a /11 for
allocations under this subsection.
Will this /11 come out of existing free space, or be half of the
existing /10, or wait for the next batch of IANA blocks?
My assumption/intention was that ARIN would take the /10 that has been
reserved under the existing 4.10 policy and divide it into two /11s one
for 4.10.1 and one /11 for 4.10.2. Other IANA returned blocks would be
placed into the 4.10.1 pool.
