What is a domain name and why do I need one?

A domain name is your unique Internet address. Most Internet sites register with the InterNIC which issues domains under the .com (commercial), .org (non profit), .net (network infrastructure), and .gov (US federal government) top level domains. There are also top level domains for every country, such as .ca (Canada), .us (United States), and .uk (United Kingdom). Domain names tend to be memorable so that people can find and return to your site. For example, if your organization was Webguru, Inc you would probably choose webguru.com.
