How to Check DNS History for Free

Q. What is a domain name server?

A. The domain name system (DNS) is a naming scheme for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each participating entity. Most importantly, it translates more readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices worldwide.


Every web2.0 has an A record that corresponds to an IP address. When you type in a domain name and press enter, the first thing your computer does is check with a domain name server (DNS) to convert the website URL into an IP address so it can find where on Earth that site resides and bring it up for you.

DNS history checks can be helpful when you are purchasing an expired domain. And the tools I suggest allow you to see all of the changes made to a specific domain name over time.

Why do we need Domain DNS history?

New domain owners often want to see the DNS history out of curiosity. Having access to an older version of your domains’ name servers would give you an idea about services that handled hosting, emails, etc.
