<div>I am trying to figure out what is the likely impact of only requiring a two year projected need claim. So my questions are regarding to what level of push back ARIN provides against two year projected need in general, and will that be sufficient
to prevent outlandishly large claims. </div>

<div>Maybe another way to get at this is to compare end user transfer stats to ISP transfer stats. </div>
<div>- what percentage of ISP specified transfers are justified by past growth? by a two year projection?</div>

<div>- do we see a greater gap between average ISP size between specified transfers that are justified by past growth vs. by a two year projection?</div>

<div style="font-family:Calibri,sans-serif"> scenarios detailed below. </div>

<div>
<div><font face="Calibri,sans-serif"> When an existing ARIN account, ISP or End-User, requests an 8.3 Recipient </font></div>
<div><font face="Calibri,sans-serif"> Transfer, ARIN will look at their historical utilization and determine the organizations </font></div>

<div><font face="Calibri,sans-serif"> requesting to have transferred and determine if that amount aligns with </font><span style="font-family:Calibri,sans-serif">their prior </span></div>

</span><span style="font-family:Calibri,sans-serif">provide regarding future plans and potential impact on growth</span></div>
<div><span style="font-family:Calibri,sans-serif"> rate.</span></div>
<div><br>
</div>
<div>=== <span style="font-family:Calibri,sans-serif">Example A</span></div>
<div><font face="Calibri,sans-serif">An existing ARIN Organization requests a /16 transfer via 8.3 transfer process.</font></div>
<div><font face="Calibri,sans-serif">They previously received the following IPv4 address space:</font></div>
<div style="font-family:Calibri,sans-serif"><font face="Calibri,sans-serif">/17 in December 2015</font></div>
<div style="font-family:Calibri,sans-serif"><font face="Calibri,sans-serif">/17 in October 2015</font></div>
<div style="font-family:Calibri,sans-serif"><font face="Calibri,sans-serif">/18 in July 2015</font></div>

<div style="font-family:Calibri,sans-serif"><font face="Calibri,sans-serif">/20 in May 2015</font></div>
<div style="font-family:Calibri,sans-serif"><font face="Calibri,sans-serif">/20 in February 2015</font></div>
<div style="font-family:Calibri,sans-serif"><font face="Calibri,sans-serif"><br>
</font></div>
<div><font face="Calibri,sans-serif">In this example, ARIN would request 24-month projections AND utilization information from the organization. We would verify they have utilized their previously received IPv4 blocks in accordance with policy
and determine their utilization trend. In this example, the organization has fully utilized their previous allocations and we note their historical utilization of 384 /24s over the past 18 months. Even though we are also taking their future plans into consideration,
their prior utilization trend is heavily weighted in justifying the newly requested /16 and they are approved. Their prior 24 months of utilization exceeds what they are requesting for the next 24 months.</font></div>
<div style="font-family:Calibri,sans-serif"><font face="Calibri,sans-serif"><br>

<div style="font-family:Calibri,sans-serif"><font face="Calibri,sans-serif">=== </font>Example B</div>
<div><font face="Calibri,sans-serif">An existing ARIN Organization requests a /16 transfer via 8.3 transfer process.</font></div>
<div style="font-family:Calibri,sans-serif"><font face="Calibri,sans-serif">They previously received the following IPv4 address space:</font></div>

</font></div>
<div><font face="Calibri,sans-serif">In this example, ARIN would again request 24-month projections AND utilization information from the organization. We would verify they have utilized their previously received IPv4 blocks in accordance
with policy and determine their utilization trend. In this example, the organization has fully utilized their previous allocations and we note their historical utilization trend of 62 /24s over the past 11 months. Their prior utilization suggests a utilization
trend of 136 /24s over a 24-month period (62 / 11 * 24mos = 135.3 or 136). The organization’s 24-month utilization trend does not meet or exceed the amount of IPv4 address space they are requesting for the next 24-month period, so the information they provide
regarding their future plans/need is more heavily weighted by ARIN staff. The information provided regarding future need paired with their utilization trend allows for an approval for the requested size (/16). </font></div>
<div><font face="Calibri,sans-serif"><br>

<div><font face="Calibri,sans-serif">=== </font><span style="font-family:Calibri,sans-serif">Example C</span></div>
<div><font face="Calibri,sans-serif">An existing ARIN Organization requests a /16 transfer via 8.3 transfer process.</font></div>
<div><br>
</div>
<div>Without providing the further background details, the requesting organization in this example has utilized their previously received blocks in accordance with policy and has a 24-month utilization trend of 65 /24s. The organization’s 24-month
utilization trend does not meet or exceed the amount of IPv4 address space they are requesting for the next 24-month period, so the information they provide <font face="Calibri,sans-serif">regarding their future plans/need is more heavily weighted
by ARIN staff. The future need projections only slightly increase expected future utilization over their prior utilization trend and a need for 100 /24s is determined for the next 24-month period. Unfortunately, the information provided regarding future need
paired with their utilization trend does not allow for the approval of the requested /16, and a /17 (closest prefix size above their demonstrated need amount) is approved instead.</font></div>

<div><font face="Calibri,sans-serif"><br>
</font></div>
<div><font face="Calibri, sans-serif"> Similarly, if a new organization comes to ARIN for an 8.3 Recipient Transfer </font><span style="font-family:Calibri,sans-serif">we </span></div>
<div><span style="font-family:Calibri,sans-serif"> would base their approval on any provider assigned space they are currently using </span></div>

</span></div>
<div><span style="font-family:Calibri,sans-serif"> It is important to note that if a new organization comes to ARIN and isn't using any</span></div>

<div><span style="font-family:Calibri,sans-serif"> on their projections.</span></div>
<div style="font-family:Calibri,sans-serif"> </div>
<div style="font-family:Calibri,sans-serif"> When we ask organization for their forward projections, we also ask them to provide </div>

<div style="font-family:Calibri,sans-serif"> end-users.) </div>
<div style="font-family:Calibri,sans-serif"><font face="Calibri,sans-serif"><br>
</font></div>
<div><font face="Calibri,sans-serif"> Given we take all of these factors into account (and noting that we don’t precisely track if </font></div>

<div><font face="Calibri,sans-serif"> 50-75% of the approval decisions made are more heavily weighted by historical utilization </font></div>

<div><span style="font-family:Calibri,sans-serif"> allows for an approval size equal to or greater than what is requested by most </span><span style="font-family:Calibri,sans-serif">organizations. </span></div>
