DNS Change Monitoring
Detect unexpected changes to NS, MX, A, SPF, DMARC and CAA records before they become an outage or a hijack.
Start free Try the free toolsIncluded from the Starter plan.
StatusDNS snapshots the important record sets of every domain and compares them on each run. Any difference — a new MX, a changed SPF include, a name server you did not expect — produces an alert with a before/after diff.
Authoritative queries
We ask your name servers directly, so changes are detected the moment they are published.
Diffs, not noise
Alerts show exactly which values were added or removed.
Severity that makes sense
NS and MX changes are critical; a TXT verification token is informational.
Delegation checks
Parent vs. child NS mismatches, lame delegations and open resolvers.
Frequently asked
Will TTL changes trigger alerts?
No — only the record values are compared.
