The domain DNS records help translate the domain name into an IP Address. Whenever a user opens a URL in the browser, it sends DNS request for translation of domain name into its corresponding IP Address. This IP helps the browser to communicate with the server to get information and resources regarding a web page. The browser cannot communicate with the server until unless the browser receives the IP behind that domain from the DNS Records.
The Domain DNS Lookup finds the DNS records propagation against the bundle of DNS servers in different locations globally. Just enter the domain name and see which DNS records your domain resolves.
