What Is DNS Monitoring?
DNS monitoring is the continuous tracking of your domain's DNS records to detect unauthorized or unexpected changes. DNS records control where your website traffic is routed, where your email is delivered, and how your domain is verified by third-party services. If someone modifies your A records, your website visitors are sent to a different server. If MX records change, your email stops working. DNS hijacking, expired domains, and misconfigured nameservers can all happen without your knowledge. Visual Sentinel monitors A, AAAA, CNAME, MX, TXT, NS, and SOA records on every check, comparing them against a known-good baseline. When any record changes, you receive an instant alert with details of what changed — often before your users notice anything wrong.
