Domainyze maintains a complete history of all DNS checks performed on your Portfolio domains. This audit trail helps you track when changes occurred and troubleshoot issues.
How to View DNS Check History
-
Navigate to Portfolio:
- Go to your Portfolio
- Click on the domain you want to review
-
Locate DNS Check History:
- Scroll down to the DNS Check History section
- This appears below the DNS Records card
-
Review Check Details:
- Each check shows:
- Timestamp when the check was performed
- Whether changes were detected
- What DNS records were affected
- Specific changes (additions and removals)
- Each check shows:
Understanding the DNS Check History Display
The DNS Check History shows all checks in reverse chronological order (newest first):
Checks with Changes Detected
- Highlighted with a "Changed" indicator
- Shows affected record types
- Click to expand and see detailed changes
- Added and removed records are clearly labeled
Checks with No Changes
- Shows normal status
- Indicates DNS records remained stable
- Timestamp of when the check occurred
What Information Is Stored?
Domainyze keeps two things: your domain's current zone state (the records as they stand now) and an append-only change log of every confirmed change. A check that finds nothing new adds no clutter, because the log grows with change, not with time.
Each entry in the change log includes:
- Detected At: Exact date and time the change was confirmed
- What changed: The specific record, its purpose (mail, delegation, website…), and whether it was added, removed, or changed
- Before and after: For a changed record, both the old and the new value
- Severity: How serious the change is, recorded at the time it happened
Retention Period
- Your current zone state is kept for as long as the domain is in your Portfolio; it is what every future check compares against, so it is never pruned.
- The change log is retained for roughly 400 days, long enough for a year-over-year view.
- Routine "no change detected" check records are kept for 90 days and then pruned automatically; checks that recorded a real change are kept.
- When a domain is removed from your Portfolio, its DNS history is also removed.
Using DNS Check History for Troubleshooting
The DNS Check History is valuable for:
1. Incident Investigation
- Pinpoint exactly when an unexpected DNS change occurred
- Correlate DNS changes with website or email outages
- Provide evidence for security investigations
2. Compliance and Auditing
- Demonstrate when configuration changes were made
- Maintain records for regulatory compliance
- Document DNS management practices
3. Rollback Information
- See previous DNS configurations
- Reference old record values when rolling back changes
- Verify that a rollback was successful
4. Pattern Recognition
- Identify recurring unauthorized changes
- Detect patterns in DNS modifications
- Track provider-initiated changes
Exporting DNS Check History
Currently, DNS check history is viewable only through the Domainyze interface. To keep your own records:
- Take screenshots of important checks
- Copy and paste change details into your documentation
- Use webhook notifications to log changes to your own system

How Often Are DNS Checks Performed?
DNS check frequency depends on your subscription tier:
- Business checks the full zone every few hours and your nameservers as often as hourly.
- Pro checks the full zone daily and your nameservers every few hours.
- Your nameservers (delegation) have their own faster lane on both plans, because a nameserver change is the most urgent event to catch.
- Checks run automatically; no manual trigger is required. The "Last checked" timestamp shows when the most recent check completed.

Limitations
- DNS check history is available only for Portfolio monitoring type
- Domains with other monitoring types do not have DNS checks
- DNS checks capture only publicly visible DNS records
- Internal or private DNS zones are not monitored
