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 describes how to use two two specific Edwards Curves
(Elliptic Curves) in conjunction with DNSSEC, namely ed25519 and

The only comment I have on this document is that the Security
Considerations section plainly states, without any reference or proof:

"Ed25519 and Ed448 offers improved security properties and
implementation characteristics compared to RSA and ECDSA algorithms"

I suggest either adding references to proofs of these statements or
alternatively just remove the sentence (since it doesn't really add
anything to the memo); the remaining paragraphs in the Security
Considerations section is what really covers what someone implementing
the memo should know or be aware of.
