I am the assigned Gen-ART reviewer for this draft. The General Area Review Team (Gen-ART) reviews all IETF documents being processed by the IESG for the IETF Chair.

Document: draft-ietf-6man-rfc4291bis-07 Reviewer: Robert Sparks Review Date: 2017-02-13 IETF LC End Date: 2017-03-01 IESG Telechat date: 2017-03-02 Summary: I have three small points for the group to consider: 1) In editing for this bis document, one bit of text was lost. RFC4291 said this in its section 2.4.5: "Global Unicast addresses that start with binary 000 have no such constraint on the size or structure of the interface ID field." Without it, the various places remaining the the document that say things like "except those that start with the binary value 0000" such as that appearing in section 2.4 of _this_ document leave the reason behind the exception a mystery. 2) At the point in the text where the modified EUI-64 format interface identifier text was moved to the appendix, this document notes that these derived interface identifiers are no longer recommended (end of 2.4.1). Consider repeating that at the first line of the new Appendix A. 3) Appendix B looks like something groups normally ask the RFC Editor to delete. If that was your intent, please add instructions to the RFC Editor so they don't have to ask. If you planned to leave it, a summary of the changes rather than a chronolog of what draft version changes were made in would be much more useful to future readers. (Such a summary would be welcome in any case.)
