Thank you for breaking out the definitions.  I support your minor change and 
agree that the sentence,  “A temporary assignment of address space provided to 
third parties shall not be considered a reassignment or a violation of the 
exclusive use criterion.” should be added to both Assignment and Reassignment.

Subject: Re: [arin-ppml] Revised/Retitled - Draft Policy ARIN-2018-4: 
Clarification on Temporary Sub-Assignments

Because of recent changes, editorial if I remember correctly, section 2.5 now 
reads as;

2.5. Allocation, Assignment, Reallocation, Reassignment

Allocation - Address space delegated to an organization directly by ARIN for 
the purpose of subsequent distribution by the recipient organization to other 
parties.

Assignment - Address space delegated to an organization directly by ARIN for 
the exclusive use of the recipient organization.

Reallocation - Address space sub-delegated to an organization by an upstream 
provider for the purpose of subsequent distribution by the recipient 
organization to other parties.

Reassignment - Address space sub-delegated to an organization by an upstream 
provider for the exclusive use of the recipient organization.

This proposal essentially adds the following sentence to "Assignment" above.

A temporary assignment of address space provided to third parties shall not be 
considered a reassignment or a violation of the exclusive use criterion.

However, I propose the following minor change to that;

A temporary reassignment of address space provided to third parties shall not 
be considered a reassignment or a violation of the exclusive use criterion.

Further, the sentence should also apply to "Reassignment". So, does the 
sentence also need to be added to "Reassignment"?  Or maybe add the following 
sentence to "Reassignment";

Excluding temporary reassignments, as discussed in the definition Assignment 
above.

Thanks

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.

Comments

Timetable for implementation:

Immediate

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.
