You are encouraged to discuss all Draft Policies on PPML. The AC will 
evaluate the discussion in order to assess the conformance of this draft 
policy with ARIN's Principles of Internet number resource policy as 
stated in the Policy Development Process (PDP). Specifically, these 
principles are:

* Enabling Fair and Impartial Number Resource Administration

Draft Policy ARIN-2018-4: Clarification on Temporary Sub-Assignments

Problem Statement:

When the policy was drafted, the concept of assignments/sub-assignments 
did not consider the use of IP addresses in hotspots, or the use of IP 
addresses by guests or employees in Bring Your Own Device (BYOD) and 
many other similar cases.

Additionally, the IETF has recently approved the use of a unique IPv6 
/64 prefix per interface/host (RFC8273) instead of a unique address. 
This, for example, allows users to connect to a hotspot, receive a /64 
such that they are "isolated" from other users (for reasons of security, 
regulatory requirements, etc.) and they can also use multiple virtual 
machines on their devices with a unique address for each one (within the 
same /64).

Section 2.5 (Definitions/Allocate and Assign), explicitly prohibits such 
assignments, stating that "Assignments... are not to be sub-assigned to 
other parties".

This proposal clarifies this situation in this regard and better define 
the concept, particularly considering new uses of IPv6 (RFC8273), by 
means of additional language added to the definition of an Assignment.

Note that the proposal text also incorporates changes made under an 
Editorial Change currently awaiting Board of Trustees review, available 
here: https://www.arin.net/policy/proposals/2017_11.html

Policy Statement:

Actual Text, Section 2.5:

• Assign - To assign means to delegate address space to an ISP or 
end-user, for specific use within the Internet infrastructure they 
operate. Assignments must only be made for specific purposes documented 
by specific organizations and are not to be sub-assigned to other parties.

New Text:

• Assignment - Address space delegated to an organization directly by 
ARIN for the exclusive use of the recipient organization. A temporary 
assignment of address space provided to third parties shall not be 
considered an assignment or a violation of the exclusive use criterion.


Timetable for implementation:


Anything else:

Situation in other regions:

This situation, has already been corrected in RIPE, and the policy was 
updated in a similar way, even if right now there is a small discrepancy 
between the policy text that reached consensus and the RIPE NCC Impact 
Analysis. A new policy proposal has been submitted to amend that, and 
the text is the same as presented by this proposal at ARIN. Same text 
has also been submitted to AfriNIC, LACNIC and APNIC.
