Document: draft-bchv-rfc6890bis-04 Reviewer: Paul Kyzivat Review Date: 2017-02-28 IETF LC End Date: 2017-03-10 IESG Telechat date: Summary: Ready with Issues General Comments: It seems that the primary intent of this document is simply to clarify the use of the term "Global". As such it should be just an editorial change. However it takes on the job of restating all the data in RFC6890 that provided the initial population of the IANA registries, and also restating all the new entries that have been added to those registries since RFC6890 was published. And the editorial changes apply to every table entry, so there are a *lot* of changes. A diff of the new document against the old one fails to match up the appropriate corresponding tables, making the document especially hard to review. I have *tried* to at least spot check the changes, especially those for registrations made since RFC6890. But I did not do an exhaustive check of every one. Issues: Major: 0 Minor: 1 Nits: 1 (1) Minor: I am concerned that the format of this document may be difficult for IANA to act on, and may increase the potential for mistakes to be introduced. The IANA format for their special purpose IP address registries contains the same information as this document but in a different format. If I understand correctly, no changes are required to the per-address content of the registries - only the introductory content and table headings need changes. But given the document format IANA will be obligated to check the content of every entry. I suggest that it might be better to eliminate duplicating the table content, and simply state what changes need to be made to the registries. (2) NIT: There is an error in the use of footnotes in Table 38. The reference to footnote "[2]" should be "[6]". (The footnote numbering has changed since RFC680, but both references were intended to be to the same footnote.)
