Search: DNS tab
The DNS tab displays DNS information related to your search. When the query contains an IP address or domain related expressions, this tab displays the passive DNS information derived from the terms. The information is collected from all analysis runs ever performed. In addition, the view also provides passive DNS information around the blocked domains and IP addresses reported on the Search: Network IoCs tab. This way you can quickly understand how the threat network infrastructure evolves over time and how it aligns with your own timeline. For example, the C&C infrastructure might already be offline by the time you were infected by the related trojan.
