DNS Sink

A DNS sink is a mechanism used to redirect or capture DNS queries to specific domains or subdomains for analysis, monitoring, or filtering purposes. Introduced as a cybersecurity measure, DNS sinks are commonly deployed by organizations to detect and mitigate malicious activity, such as malware infections, phishing attempts, and command-and-control communications. When DNS queries are redirected to a sinkhole server, they can be logged, analyzed, and used to identify potential threats or security breaches. DNS sinks can also be used for network monitoring and troubleshooting purposes, allowing administrators to track DNS traffic patterns, identify misconfigurations, and troubleshoot connectivity issues. By deploying DNS sinks strategically within their networks, organizations can enhance their cybersecurity posture and protect against DNS-based attacks and data exfiltration attempts.
