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

Tue Apr 24 15:12:41 EDT 2018

Hi David,

Thanks for the inputs!

If there is a pointer to that text update, I’m happy to review my proposal to accommodate to it.

I think I need to understand that text update also to consider your comment regarding if it need to go to section 2 or section 6, or something in each section …, so making sure that either is IP version agnostic or we clarify that part of the text is for IPv6 only.

I guess there are several ways to achieve the same goal.

Regards,

Jordi

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

I note that the text in question is the subject of an editorial change that the AC has recently forwarded to Board for review, at a minimum the policy text need to be updated to account for this editorial change. Further, I do not support the text as written.

I support a change to section 2 that is not quite so IPv6 specific and focused more on the idea that providing hotspot, guest access, or other such temporary access does not necessitate the making of re-assignments from a policy perspective.  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.

Thanks.

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
 * Technically Sound
 * Supported by the Community

Draft Policy ARIN-2018-4: Clarification on IPv6 Sub-Assignments

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.

5.    Policy Statement

Actual Text

•    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

•    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.

The fact that a unique address or even a unique /64 prefix is non-permanently provided to third parties, on a link operated by the original receiver of the assignment, shall not be considered a sub-assignment. 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.

6.    Comments

a.    Timetable for implementation:

Immediate

b.    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.
