And in fact if you have enterprise-wide visibility on DNS requests, you have the opportunity to detect the use of an IP that was not returned in a request. Making it immediately suspect.
I’ve personally been engaged in incident response and in many scenarios DNS is a control mechanism for malware, or uses it for various purposes. It’s often a key piece of evidence for reconstruction of an incident.
