[arin-ppml] Revised - ARIN-2024-7: Addition of Definitions for General and Special Purpose IP Addresses

Mon Mar 17 09:57:48 EDT 2025

Hi all,

Since my last request for support for this policy I have heard from two community members who support abandoning the policy in its current iteration. The suggestion was to include additional policy text with the definition acting as supporting language. My understanding from this feedback is that proposing just a new definition is not enough of a substantiative change without additional policy language.

I would like to hear from the community if that is the general consensus for this policy, or if there is support for moving forward with this policy in its current state.

Thanks,
Kaitlyn

Hello PPML,

I am soliciting any additional feedback the community may have on the below policy. Please note, we received one comment suggesting that rather than using the term "2.18 Reserved IPv4 and IPv6 Addresses" we could instead use the term "Defined Purpose IPv4 and IPv6 Addresses." If anyone in the community feels this is better language (or has a suggestion for different language) please respond accordingly.

If the community are able to agree on language surrounding a definition there would be subsequent policies to update the language in the NRPM to match. The author provided an example of what that may look like as follows:

"Section 4.3.2

Change paragraph 1 text
FROM: “End-user organizations without an IPv4 allocation from ARIN qualify for
an initial allocation of ARIN’s minimum allocation size.”
TO: “End-user organizations without a Reserved (or Defined Purpose) IPv4 allocation
from ARIN qualify for an initial allocation of ARIN’s minimum allocation size.”"

Given the lack of responses we've received thus far I would also like to pose the question to the community: do you feel that this is a policy the AC should continue to work on?

Again, if the community feels strongly one way or another please respond in the PPML so we can gain a sense of whether or not this policy has community support.

Much appreciated,
Kaitlyn

Draft Policy ARIN-2024-7: Addition of Definitions for General and Special Purpose IP Addresses

Problem Statement:

The Number Resource Policy Manual (NRPM) often treats general purpose and special purpose IP addresses differently. Unfortunately, we don’t have a convenient to use term to describe these categories, so policy often becomes either excessively wordy or does not correctly capture the intent. Examples of this can be found in section 4.1.8 of the NRPM, and in (currently pending) Draft Policies ARIN-2023-8 (where the fact that 4.4 and 4.10 space isn’t counted against an organization is repeated numerous times) and ARIN-2022-12 (where the text does not exclude 4.4 and 4.10 allocations from being counted against an organization, but it is the intent that those allocations should be ignored). Additionally, temporary allocations under section 11 are rarely carved out, even when 4.4 and 4.10 are, even though it is likely the policy’s intent that these too should be ignored.

Policy Statement:

Add the following definition to Section 2

2.18 Reserved IPv4 and IPv6 Addresses
Addresses that are reserved by ARIN for specific purposes including, but not limited to; maintaining critical infrastructure, facilitating IPv6 deployment, or temporary experimental purposes as approved by ARIN.

Timetable for Implementation: Immediate.
