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. This document specifies updated DNSSEC algorithm recommendations. It includes updates on DNSKEY, DS and CDS algorithms. The recommendations are similar to the methodology defined for IPSec algorithm recommendations, which have been useful to implementors and users. The actual algorithm recommendations (MUST, RECOMMENDED, NOT RECOMMENDED, MAY, MUST NOT) are in line with current general algorithm guidance, and match the goals set forth in the document. I make no further comment on them as the details of the recommendations have likely to have been finely honed through debate within the working group. I believe the document is ready to publish.
