DNS Monitor
Monitor DNS records for your domains and detect unauthorized or unexpected changes.
How it works
UptimeGuard performs a DNS lookup for the specified domain and record type. If the resolved value doesn't match the expected value, the monitor goes down and an alert is triggered.
Configuration
| Setting | Description |
|---|---|
| Hostname | The domain to query (e.g. example.com). |
| Record Type | A, AAAA, CNAME, MX, TXT, NS, or SOA. |
| Expected Value | The expected DNS record value. If set, the check fails when the resolved value differs. |
Use cases
- Detect DNS hijacking or poisoning
- Verify DNS propagation after changes
- Monitor MX records for email deliverability
- Ensure CDN CNAME records are correct
