If would like to check what name servers (DNS) your site's domain name is currently using, simply do the following:
1.Go to http://www.domaintools.net/
2.In the field that says "Whois Lookup", enter your domain name.
3.Click "Submit."
4.The results will show the name servers your site is using, along with information about your domain registrar (the company where you bought your domain name).
NOTE: If you recently made changes to your domain information, it can take up to 72 hours to see this new information.
