DNS History

The DNS History page shows a timeline of DNS record changes for a domain. Access it from the gear menu on the Domain Overview page.

What It Shows​

Palisade periodically snapshots DNS records for your monitored domains. The DNS History page lets you browse these snapshots to see exactly when and how records changed.

Filtering​

By Record Type​

Filter snapshots to show changes for specific record types:

  • SPF
  • DMARC
  • BIMI
  • MX
  • DKIM
  • NS

By Date Range​

Select a time window to narrow results. Options range from 14 days to 60 days.

Viewing Changes​

Each snapshot entry shows:

  • Date and time of the snapshot
  • Record type that changed
  • Record value at that point in time

Click on a snapshot to open a detail view. When comparing consecutive snapshots, a diff view highlights exactly what changed between them — making it easy to spot unintended modifications or confirm that an update took effect.

Use Cases​

  • Audit trail — track who or what changed DNS records and when
  • Troubleshoot regressions — identify when a working configuration was broken
  • Verify propagation — confirm that DNS changes have taken effect
  • Detect drift — spot unauthorized or accidental DNS modifications
