| A
domain name consists of two or more words separated by
a period. The last word (the far right) is called a "top-level
domain". Here are some common top-level domains and
their use:
·COM
Used
for commercial entities. It is the most popular top-level
domain. Anyone can register a .com domain.
·NET
Originally used for networking organizations such as
Internet Service Providers and backbone providers. Today,
anyone can register a .net domain.
·ORG
Designed for miscellaneous organizations, including
non-profit groups. Today, anyone can register a .org
domain.
·EDU
Four-year, accredited colleges and universities.
Country
Codes
Other top-level domains include those for countries
(.CA for Canada, .UK for the United Kingdom, .HK for
Hong Kong, etc.), which are based on the International
Country
Codes
Other top-level domains include those for countries
(.CA for Canada, .UK for the United Kingdom, .HK for
Hong Kong, etc.), which are based on the International
Standards Organization's 3166 standard for country abbreviations.
To
the left of the top-level domain is what is called the
"second-level domain." In worldindia.com,
"worldindia" represents a second-level domain
within the top-level domain of .com.
It
is also possible to have a domain name in the form of
something.worldindia.com. In this case the "something"
is called a "host" name or a "sub-domain".
It is not necessary to register a host or sub-domain
with a registry before being able to use it. |
