DNS monitoring checks your A, MX, NS, and TXT records and alerts you when anything changes. Unexpected DNS changes can redirect traffic, break email, or indicate a compromise.
⚙️How it works
Uptrue resolves all major record types for your domain on each check cycle. If any record differs from the previous snapshot, an alert fires with a diff of what changed.
✓What Uptrue checks
- A records (IPv4)
- MX records (mail routing)
- NS records (nameservers)
- TXT records (SPF, DMARC, verification)
⚠Alert conditions
- Any DNS record changes from baseline
- DNS resolution failure
Why this matters
DNS changes propagate globally in minutes. A misconfiguration or hijack can silently redirect your users or drop your email. Early detection is critical.
