Frequently Asked Questions
How far back does your DNS history go?
Our DNS archive depth varies by domain. We started systematic DNS archiving in recent years, so historical data availability depends on when we first began monitoring each domain.
How often do you update DNS records?
We scan DNS records approximately once per week for most domains. High-priority domains may be checked more frequently, while less active domains might have longer intervals.
Is your DNS archive complete?
No, our archive is not complete. It's built based on our indexing robot's crawling patterns and may miss some changes that occur between our scanning intervals.
Can I see deleted or expired domains?
Yes, our archive may contain historical records for domains that are no longer active, providing insights into their previous configurations before expiration or deletion.
How accurate is historical DNS data?
Our historical data reflects DNS configurations at the time of our scans. However, DNS changes between scans may not be captured, so consider this when analyzing historical patterns.
Can I export historical DNS data?
Yes, you can export current and archived DNS records in various formats. Historical data export capabilities depend on the specific domain and available archive depth.
