Reviewer: Barry Leiba Review result: Ready This document fills a gap created by RFC 6275 by creating a necessary IANA registry. The document is well written and ready to go, with no security implications that I can imagine. I read Al Morton's OpsDir review. Commenting on that: - I think the document can go ahead with or without the changes that Al suggests, but... - I agree that it'd be useful to show the reserved bits in the registry table, except that I'd give the reference for it as RFC 4861, not 6275. - The text in Section 4 already does say what the registration policy is, and I don't think "or IESG Approval" should be added. - I don't think it's necessary to add "updates 6275", though I wouldn't object to it. - I agree that adding section references would be nice. I found the fields easily by searching on their names, but I'm a general fan of using section references to make things clearer to readers. -- Barry
