Internet is based on IP addresses, not domain names, every Web server requires a Domain Name System (DNS) server to translate domain names into IP addresses. Here are just a limited number of such domains. For example:

• .gov - Government agencies

• .edu - Educational institutions

• .org - Organizations (nonprofit)

• .mil - Military

• .com - commercial business

• .net - Network organizations

• .ca - Canada

• .th - Thailand
