If would like to check what name servers (DNS) your site's domain name is currently using, simply do the following:
- Go to http://www.domaintools.com/
- In the field that says "Whois Lookup", enter your domain name.
- Click "Submit."
- 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 48 hours to see this new information.
