SecurityTrails enables you to explore complete current and historical data for any internet assets, including domains and IP addresses.
There are various situations where this may be useful, such as when you need to revert a DNS change but don't have the previous details or if you need to determine where a domain was pointing at a previous point in time.
Here we cover the steps to use SecurityTrails to review a domain's DNS history.
