[arin-ppml] ARIN-2024-5 Rewrite of NRPM Section 4.4 Micro-Allocation - Community Questions

[Chris Woodfield]

As the policy shepherd, I’ll mention that the current silence on this creates ambiguity for ARIN staff, and clarity is needed.

The current proposal contains the following language: “Allocated addresses may … be used to operate *all* of the Internet Exchange’s infrastructure”. This implies the IXP’s public website, route servers/looking glasses, customer portals, and other corporate infrastructure may be numbered out of the 4.4 allocation. Is that the authors’ intent? If so, is the community in support?

Thanks,

-Chris

And another /24 for the LAN which is fine. So an IXP would always consume a /23 while 50% is known to be probably wasted, unless properly justified.
