[arin-ppml] Sections 6.4.1 and 6.4.2 - Potential Simplification (from the NRPM Working Group)

Dear ARIN Community Members,

In our continuing effort to simplify the NRPM, we are also considering the retirement of sections 6.4.1 and 6.4.2.

We believe that section 6.4.1 is out of scope since it constitutes a legal conclusion regarding IPv6 addresses not constituting property, rather than policy. Section 6.4.2 is a general statement regarding the lack of guarantee of the routability of address space and also provides that RIRs (and not just ARIN) "must apply procedures that reduce the possibility of fragmented address space which may lead to a loss of routability". To the extent that this section validly articulates policy statements, it applies more broadly to both IPv4 and IPv6 resources, and the statement in the NRMP should only apply to ARIN. In fact, a proper routability constraint statement limited to ARIN is already embedded in Section 1.3 of the NRPM, and thus not needed in Section 6."

Community feedback and any proposals to address these sections are welcome."

Kind regards,


Chris Tacit
NRPM Working Group Chair
