Ever encounter something odd such as a well-known site disappears, an e-mail to a good address bounces or a customer says your site is down when it isn’t? Often the problem stems from DNS, the system that maps a Web name (e.g., www.yahoo.com) to its corresponding Web location or IP address (e.g., 66.94.231.98). The DNS Stuff page provides a bevy of free tools for quick DNS checks.
