What is domain DNS history?

DNS history shows which IP addresses, mail servers and verification records a domain resolved to over time. Infrastructure migrations, server changes and CDN cutovers can be traced through these records.

This page lists the visible records collected from several public passive DNS sources in chronological order. Each record includes its type, label and value together with first and last seen dates.

Historical records are useful for domain security audits, post-migration verification and reputation research. Use the DNS lookup on the home page to see the current configuration.

FAQ

DNS history FAQ

What is DNS history used for?
It reveals a domain's former IP addresses, mail servers and verification records. It helps you check whether old records survived a migration, or when the underlying infrastructure changed.
Why are only some historical records visible?
Historical data is collected from several public passive DNS sources. These sources only share their own scan history, so not every record shown by paid services appears here.
Do historical records show the current configuration?
No. Historical records reflect how the domain looked in the past, not its current configuration. Use the DNS lookup for the current records.
