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 informational draft describes the operational practices for administrating a DNSSEC environment.  Specifically the management of keys and signatures in DNS.  The draft intends to obsolete RFC 4641. The security considerations section does exist and is somewhat terse in its explanation of mitigating spoofing and DoS attacks.  This should be expanded or at least a reference made. General comments: None. Editorial comments: Consistency: SEP is expanded, but not DS. s/purposes X will somewhere/purposes, X will be somewhere/ s/such as e.g.  RFC 5011/e.g. RFC 5011/ Shawn. --
