A DNS monitor stores the records of a domain and alerts you when they change. That catches a mistaken edit, an expired DNS provider account or a hijacked record before mail stops or visitors land somewhere else.
Create the DNS monitor
- Open DNS monitors and choose Create DNS monitor.
- Give it a name and enter the domain name, such as
example.com. - Tick the notification handlers that should hear about changes.
- Choose the check interval.
- Under Advanced settings, select the record types to query: A, AAAA, CNAME, CAA, MX, NS, SOA and TXT.
- Choose Create.
Which records to watch
- A and AAAA for where the site points.
- MX for where mail goes.
- NS for who controls the domain’s DNS.
- TXT for SPF, DKIM and DMARC, which decide whether your mail is delivered.
Planned DNS work will also trigger an alert. That is expected: it confirms the change went out. Read how to detect changed or hijacked records, or more on DNS monitoring.
