Hi Russ, I have four questions before following the request. Qs below; please answer, [rfc2050bis-00] > The administrative structures of the Internet Numbers Registry System > described in this document are largely the result of the interaction > of operational practices, existing routing technology, number > resource assignments that have occurred over time, and network > architectural history. Further discussion and analysis of these > interactions are outside the scope of this document. 1) Is this a historic document of Internet numbers or informational, you mention history of what *occured over time*, but does the document show dates? 2) The operational practices you mentioned and existing routing technology, do they have technical purposes? if yes I think it will be in scope to provide the purposes of thoes practices in the applicability statement section. 3) Was this document's concerns discussed in IETF Routing Area or a related document produced by the area? if yes please refer, if not I recommend to be discussed. 4) What is the reason of out of scope, and not even refering to a reference best paractice? Will there be IETF discussion and analysis of these interaction in future? I think if informational document some recommendations and analysis are helpful. Regards AB
