I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written primarily for the benefit of the security area directors.  Document editors and WG chairs should treat these comments just like any other last call comments. The document is basically just about acronyms to simplify DANE conversations Th e document appears ready for publication. The security consideration section is sufficient and there are no security issues with this document. There are only two small nits / spelling issues: in section "Abstract": - s/Experience has show that/Experience has shown that - speaking of acronyms, the first mention of TLSA should spell it out. Thank you and best regards. Tobias
