An Introduction to
Domain Names
Your domain name is your
public name in the world, nobody else will have your exact name (maybe
similar but never the same exact name) and that is what
identify/difference you from the rest of the people.
The advantage of this
World Wide Web thing is that you register you name and everybody in the
world can see it/find you, you don't have to register in every country
to do business with people there (even it is highly recommended to get
cTLD's (country Top Level Domain) names, it is not mandatory).
Another this is that
even your name is universal, it is assigned to an specific group of
numbers, called: IP ADDRESS. That IP Address is a set of numbers
that a DNS (Domain Name Service) will translate everytime you are
looking for something.
It is impossible that
your computer «knows» where is XYZ or ABC company located in the world,
so when you type a domain in your browser or send an e-mail, your
computer ask your local DNS where is that address... most of the
time your computer will not know for the first time where to proceed, so
it will ask its parent DNS and subsequent until it finds the
registration name and its corresponding IP Address, that way the
computer will start to jump between all the routers and system around to
world until it finds the IP ADDRESS and then resolves the name...
the magic is that: EVERYTHING HAPPENS in seconds!!!
Domain names are typically
categorized by their extension, which is their identifying code. The three
most popular types of Top Level Domains (TLDs), which are domains that are
not associated with a country, are:
.COM: Short for .commercial.
Domain names with the .com extension are by far the most popular, and can
be purchased by any individual or business. .
.NET: Short for .network,
this domain extension was originally designed to be used by technical Web
sites. However, domains using this extension can be registered by anyone.
.ORG: Short for
.organization. Originally designated for non-profit firms and any other
organizations that did not fit under the .com or .net extension, any
individual or business may now register a .org domain name.
As explained aboce,
there are also specific COUNTRY CODE Domain names (cTLDs) and they will
have also sub-divisions...
COUNTRY LEVEL DOMAINS
Domain names can also be
assigned using country extensions. Each country has its own domain
extension; Costa Rica has .cr, Canada, for example, is .ca, while Japan has been assigned .jp. Most countries have specific rules surrounding exactly who can register
domains using their extension and for what purpose; it’s therefore
important to look before you leap. Also remember, some country level
domains have other «meanings» and can be used do to associations like:
.cr (Costa Rica)
.ws (WebSite and originally Western Samoa)
.it (Information Technology and originally Italy)
.es (Spanish word for «IS» and originally Spain = España)
.co (Colombia)
.ca (Canada)
.us (United States of America)
.no (Norway)
ALTERNATIVE DOMAIN NAMES
The Internet Corporation for
Assigned Names and Numbers (ICANN), the organization responsible for the
administration of TLDs worldwide, recently approved several new extensions
that are not specific to any country. These are:
.aero
(air lines and similars)
.biz
(business)
.coop (cooperatives)
.info (informative sites)
.museum (museums)
.name (personal usage of name)
.pro (professionals)
Each has been designed for a
specific use, and is accompanied by certain restrictions. You can find
more information about these TLDs here:

OTHER DOMAIN EXTENSIONS
In searching for your domain
name, you may encounter Web sites offering extensions like .xxx, .free and
.mp3. These are not true extensions endorsed by ICANN; rather, they rely
on software solutions to guarantee their accessibility to users. Because
ICANN has not approved any of these extensions, however, users that do not
have the correct software cannot access sites using these names;
therefore, they should be used for supplemental purposes only.
Although .com, .net and .org
are typically the most visible and talked-about extensions, they are not
the only ones available for use. From a functional perspective,
country-level domains work just as well as any TLDs, and alternative
extensions work just as well. Therefore, don’t necessarily settle for a
mediocre TLD when you can get a better one using a different extension.
