Reviewer: Nagendra Nainar Review result: Has Issues Hi, I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts per guidelines in RFC5706. Comments that are not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments. Overall Summary: This draft is attempting to summarize the problems related to the current practice for extending DHCPv6 protocol. This document does not propose any solution, framework, or protocol extensions and so it does not raise any backward compatibility challenges or operational considerations. While the document does not raise any operational/management considerations, I am choosing "Has Issues" as the overall draft may need substantial changes. Few comments below: The manageability, security, privacy protection, and traceability of networks can be supported by extending the DHCPv6 protocol according to requirements. This document provides current extension practices and typical DHCPv6 server softwares on extensions, defines a DHCPv6 general model, discusses some extension points, and presents extension cases. --> The abstract is not clear in reflecting what the draft is about. Based on the above, this draft appears to be discussing current extension practice, extension points, and cases which is more like a survey document that summarizes what we have currently. This being a draft that attempts to document the problem statement, it will be good to reflect the same in the abstract. --> The Introduction section may need some rework. It is not clear in defining what is multi-requirement extension problem. --> I think, a section (or sub-section) clarifying what is multi-requirement extension with an example use case will help the readers to better understand the objective of this document.
