The most frustrating part about DNSSEC is that trying to pin down what it is and what it is not, what it is trying to do and what it is not is like trying to nail jello to a wall.
Whenever an issue is raised with the DNSSEC protocol, someone immediately shoots back the reply 'well we are not trying to solve that problem'. Which is of course really easy when there is no clear statement of what real world security issues that DNSSEC is trying to deal with. Blocking one attack does not come close to justifying the cost of DNSSEC deployment. Is DLV a part of DNSSEC or not? I am not sure. DLV is presented as being a stopgap, an interim measure to go away with full DNSSEC deployment. What I do know is that I want to use secure DNS in devices that are not capable of performing public key cryptography. And even if every end point device is capable of performing RSA2048 operations in acceptable time, I do not want to push my trust management criteria out to my network endpoints.
