[arin-ppml] Draft Policy ARIN-2018-4: Clarification on IPv6 Sub-Assignments

Maybe a better way to approach this question would be, are the use cases at issue here (guest wifi hotspots, etc) a business activity that one would consider a primary line of business for the organization?

I’m wondering if a better way to approach this would be to ask the question as to whether or not the assignment of resources to third-party end users is an action that’s considered a product that the organization/company provides, or an ancillary service. In most cases, wifi hotspots clearly are ancillary, and as such, I would not see any issue with considering those allocations direct assignments. If wifi connectivity is a substantial revenue-generating service for the organization, however, then I agree that an allocation is a better fit.

This includes, for example, guests or employees (devices or servers), hotspots, and point-to-point links or VPNs. The provision of addressing for permanent connectivity or broadband services is still considered a sub-assignment. Only the addressing of the point-to-point link itself can be permanent and that addressing can't be used (neither directly or indirectly) for the actual communication.

Furthermore, such uses are not in conflict with the conditions of an assignment (made by ARIN) or re-assignment (made by an ISP or LIR). Also, If the details of RFC8273 need to be mentioned at all, they should be someplace in section 6, not in section 2, the definitions of assign, allocate, re-assign and re-allocate should remain agnostic about IP version.

>> Problem Statement:
>> 
>> When the policy was drafted, the concept of assignments/sub-assignments did not consider a practice very common in IPv4 which is replicated and even amplified in IPv6: the use of IP addresses for point-to-point links or VPNs.
>> 
>> In the case of IPv6, instead of unique addresses, the use of unique prefixes (/64) is increasingly common.
>> 
>> Likewise, the policy failed to 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.
>> 
>> Finally, the IETF has recently approved the use of a unique /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 a new paragraph.

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.
