Components of a domain name


A domain name has a number of components.

For example, this domain name:

www.address.com.cn

has the following components:

www indicates it is a worldwide web address

address is the domain name that you register

com indicates the category of domain name you have registered, and is called a top level domain name
 
cn indicates the country of origin (also known as a country code top-level domain), namely Mainland China in this example.
 

Other top level domain names include:

biz  indicates a business
edu  indicates an educational institution
gov  indicates a government department
org  indicates a non-profit organisation

 

In Hong Kong it is not unusual for a domain name to be registered without any top level domain name. In that case, the domain name could be registered as:

www.address.hk

 

It is not necessary for every domain name to indicate the country of origin. Domain names that originate in the United States do not have a country of origin component in the domain name.

 

The following domain name for example does not show a country of origin:

www.address.com

 

Anyone can register a domain name without a country of origin, not just applicants in the United States.
