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

[Owen DeLong]

I don’t think there’s any gain from this proposal.

The policies still need to spell out the restrictions on the use of such address space explicitly in the relevant section of the policy and I don’t see anywhere where referring to it generally would gain much.

I think it’s mostly harmless, though the potential for unintended consequences seems to exceed the value IMHO.

> 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.
