This policy seems very sound. It is codifying an undocumented practice of ARIN 
staff and by putting it into policy it makes it clear to entities that were 
only browsing the policy that this is allowable, likely expanding (even 
modestly) the number of entities that would seek to swap a larger block for a 
smaller one and potentially get those underused blocks into circulation where 
they can be used. I supported this policy at the ARIN 50 meeting and continue 
to support it during last call.

I have a more general question related to the policy, and it may have been 
previously discussed and I’m unaware since I’m new:

- The problem statement outlines a situation where some entities have created 
new orgs to receive the new block and work around the existing policy language. 
While this policy makes that workaround “no longer needed” - there are other 
reasons a resource holder may create an organization to receive a secondary 
block or get on the waitlist. What happens when those reasons are abusive in 
nature? (e.g., an org built to circumvent the policy in a more nefarious way.) 
More of an academic question to try to understand where the limits of policy 
and practical implementation intersect.


Thank you -


Doug

Recommended Draft Policy ARIN-2020-6: Allowance for IPv4 Allocation “Swap” 
Transactions via 8.3 Specified Transfers and 8.4 Inter-RIR Transfers

AC Assessment of Conformance with the Principles of Internet Number Resource 
Policy:

Draft Policy 2020-6 is fair, impartial, and technically sound. The intent of 
this policy is to eliminate confusion by codifying existing processes for 
downsizing IPv4 allocations and assignments within the written policy of the 
NRPM. It has the apparent support of the community.

Problem Statement:

Organizations wishing to “swap out” a larger block for a smaller one in the 
interest of avoiding deaggregation (as opposed to breaking up their existing 
block and transferring only a part of it) are forbidden by existing 8.3 policy 
from being the source of the transfer for their larger block after receiving a 
smaller one for 12 months after receiving the smaller block. In practice, ARIN 
staff has been allowing orgs to transfer out blocks after receiving smaller 
ones inside of the 12-month window, but many ARIN resource holders are not 
aware of this. Some resource holders have worked around the restriction by 
creating a new org to receive the smaller block, but this practice has 
implications on waitlist policy, as the new org is now technically eligible to 
apply for wait-list space while the original org cannot.

Similar language is present in NRPM Section 8.4, as such, the practice should 
be sanctioned for those types of transfers as well.

Policy Statement: Clarify the conditions under 8.3 and 8.4 that explicitly 
allows transfer of a larger block in exchange for a smaller one as part of a 
renumbering plan by making the following changes in 8.3, 8.4, and 8.5:

8.5.5. Block Size

Organizations may qualify for the transfer of a larger initial block, or an 
additional block, by providing documentation to ARIN which details the use of 
at least 50% of the requested IPv4 block size within 24 months. An officer of 
the organization shall attest to the documentation provided to ARIN.

Add:

8.5.5.1- Transfer for the Purpose of Renumbering

Organizations with larger direct allocations or assignments than they require 
may receive transfer of a smaller block for the purpose of renumbering onto the 
smaller block if they transfer the entire larger block to a qualified recipient 
under section 8 within one year of receipt of transfer of the smaller block. If 
the larger block is not transferred within one year of receipt of the smaller 
block, the organization will be ineligible to receive any further transfers 
under this section until the larger block is transferred.

8.5.5.1.1 Smaller Block Size

Organizations may qualify to receive transfer of a smaller block by providing 
documentation to ARIN which details the use of at least 50% of the smaller 
block size within 24 months. Current use of the larger block may be used to 
satisfy this criteria.

Current text:

8.5.6. Efficient Utilization of Previous Blocks

Organizations with direct assignments or allocations from ARIN must have 
efficiently utilized at least 50% of their cumulative IPv4 address blocks in 
order to receive additional space. This includes all space reassigned to their 
customers.

Add:

8.5.6.1 Transfer for the Purpose of Renumbering

Organizations receiving transfer of a smaller block under section 8.5.5.1 may 
deduct the larger block they are transferring to a qualified recipient when 
calculating their efficient utilization of previous blocks under section 8.5.6.

Current Text:

Sections 8.3 and 8.4, under “Conditions on Source Of the Transfer”: “The source 
entity must not have received a transfer, allocation, or assignment of IPv4 
number resources from ARIN for the 12 months prior to the approval of a 
transfer request. This restriction does not include 8.2 transfers.

Change to:

With the exception of M&A transfers under section 8.2, the source entity must 
not have received a transfer, allocation, or assignment from ARIN for the past 
12 months. This requirement may be waived by ARIN for transfers made in 
connection with a renumbering exercise designed to more efficiently utilize 
number resources under section 8.5.5.1.

Timetable for Implementation: Immediate
