Document: draft-ietf-acme-ip-06 Reviewer: Robert Sparks Review Date: 2019-06-03 IETF LC End Date: 2019-06-12 IESG Telechat date: Not scheduled for a telechat Summary: Ready for publication as a proposed standard rfc. One minor nit: The security considerations section reads oddly. I'm not sure what it means for an extension to deviate from a threat model. I think you want to say "does not add to" rather than "does not deviate"?
