Re: [sig-policy] prop-124-version 5: Clarification on IPv6 Sub-Assignments

[JORDI PALET MARTINEZ <jordi.palet@consulintel.es>]

Dear Satoru, all,

 

First of all, thanks a lot for your inputs!

 

Let me try to clarify this.

 

The text of the problem statement has been the same (maybe minor variations) across the 4 previous versions, so it is difficult to understand what is not clear now, which can have been addressed before.

 

In any case, what it matters in a policy proposal, is the policy text and the objective of the change.

 

What happens with current policy is that if you’re an enterprise with assigned addressing space, you can only use it for your own infrastructure and within it.

 

If you want to have a “guest” WiFi (visitors in the company, students in a University), or you need to provide it via VPN, or point-to-point links, it is not allowed. The problem statement just provides more examples and cases, but everything boils down to the same.

 

I don’t think that was the intended purpose of the original policy, but that text has been carried out from IPv4 policies, and in most of the cases, there you don’t have the same problem because you’re providing to the visitors or students private addressing space behind a NAT.

 

Let me know please, if this is clearer as a “short” for the problem statement and objective of the policy change.

Regards,

Jordi

Dear Colleagues,

 

I am Satoru Tsurumaki from Japan Open Policy Forum Steering Team.

 

I would like to share a feedback in our community for prop-124,

based on a meeting we organized on 12th Feb to discuss these proposals.

 

Many participants expressed a neutral for the proposal with reasons that

the problem in the current policy is something vague.

 

And a few opposing comments were expressed with same reason as above.

 

 

Best Regards,

 

Satoru Tsurumaki

prop-124-v005: Clarification on IPv6 Sub-Assignments

---

Proposer: Jordi Palet Martínez
jordi.palet@theipv6company.com

1. 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 IPv4, typically, this is not a problem because the usage of NAT.

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 hotspots (when is not an ISP, for example, associations or
community networks), or the use of IP addresses by guests or employees
in Bring Your Own Device (BYOD) and many other similar cases.

One more case is when an end-user contracts a third-party to do some
services in their own network and they need to deploy their own devices,
even servers, network equipment, etc. For example, security surveillance
services may require that the contractor provides their own cameras,
recording system, even their own firewall and/or router for a dedicated
VPN, etc. Of course, in many cases, this surveillance system may need
to use the addressing space of the end-user.

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).

2. Objective of policy change

Section 2.2.3. (Definitions/Assigned Address Space), explicitly prohibits
such assignments, stating that “Assigned ... may not be sub-assigned”.

This proposal clarifies this situation in this regard and better define
the concept, particularly considering new uses of IPv6 (RFC8273), by means
of new text.

It also clarifies that the usage of sub-assignments in ISPs, data centers
and similar cases is not allowed.

3. 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 APNIC. Same text
has also been submitted to AfriNIC (already reached consensus), LACNIC
and ARIN.

4. Proposed policy solution

Add a new paragraph after the existing one in 2.2.3.

Actual text:

2.2.3. Assigned address space
Assigned address space is address space that is delegated to an LIR,
or end-user, for specific use within the Internet infrastructure they
operate. Assignments must only be made for specific, documented purposes
and may not be sub-assigned.

New text:

2.2.3. Assigned address space
Assigned address space is address space that is delegated to an LIR,
or end-user, for exclusive use within the infrastructure they operate,
as well as for interconnection purposes.

The address space assignment is only for use by the original holder of said
assignment, as well as for third party devices, as long as they are
operating
within the original holder infrastructure.

Sub-assignments are not allowed outside that infrastructure (for example
using
sub-assignments for ISP customers), neither for providing addressing
space to
third parties in data-centers (or similar cases).

5. Advantages / Disadvantages

Advantages:
Fulfilling the objective above indicated and making sure to match the real
situation in the market.

Disadvantages:
None foreseen.

6. Impact on resource holders

None.
