A Domain name is used to identify one or more IP addresses.
For example, the domain name microsoft.com represents about a dozen IP addresses. A Domain Name is used in URLs to identify particular Web pages.
For example, in the URL http://ameawebdesign.com/website-design/, the domain name ameawebdesign.com
Every domain name has a suffix that indicates which top level domain (TLD) it belongs to. There are only 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
Because the 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.
