What is a Domain
Name?
by
Instant Domain Registration Center
Each web site on the
internet has a numeric address that functions like coordinates on a map.
Instead of pointing to a geographic location on earth, these numeric addresses,
called IP addresses, point to a geographical location on the Internet.
Computers have no problems with locating and remembering numeric addresses.
In contrast, most humans have trouble remembering long complicated sequences
of numbers. So, to make surfing the web easier, the domain name system
was invented. This system allows people to use easy to remember names
for web sites instead of those number sequences.
So, in short, a domain
name is nothing more than an alias for a numeric web address. It's really
that simple. If you like to get a more technical explanation, read on!
Domain names are organized
according to specific hierarchy, called the DNS naming hierarchy. The
DNS naming hierarchy is a tree-like arrangement with ascending authority.
Each domain represents a distinct chunk of the naming hierarchy and is
managed by a single administrative entity. The root of this "tree"
is called "." (the dot in DNS jargon) and beneath it are the
top-level (or "root-level") domains. The top-level domains are
relatively fixed.
For historical reasons
(the Internet started in the United States, funded by the Department of
Defense in the 1960s, yes, that's nineteen-sixties,
well before the birth of personal computers), there are two sorts of top-level
domain names. In the US, generic top-level domains(gTLDs) used to describe
organizational and political structures and are usually given three-letter
names. Over the past few years, a number of these gTLDs have become "unresticted",
i.e. anyone can register a domain in that gTLD. You do not even have to
reside in the US or be a business entity. For domains outside the US,
two-letter ISO (International Organization For Standardization) country
codes are used.
Here are the current
gTLDs. Over the next few months, there will likely be new additions to
this list.

Thus, anyone can register
a .com, .net or .org domain. In fact, many companies now register all
three domains in order to truly secure their web identity.
To apply for a domain
name, you must have secured at least two name servers for handling DNS
inquires about your domain on the Internet. Thus, for individuals and
companies who do not have full time connections to the Internet and who
do not have these expensive name servers, it is easier to submit your
application for a domain name through an Internet service company like
Instant-Domain who can provide you the pre-requisite name servers and
handle all the registration details for you.
