Domain Name Basics
One of the most exciting activities associated with starting a
web site is picking the domain name. With online tools available to
help you search for and register available names, it has become a
quick and easy process to stake claim to a domain. But what exactly
is a domain name? What does it represent? This article digs deeper
into the origins and definitions of internet domain names.
Just Like an Address
When you visit a website using your browser, you enter the location
of the website which is usually denoted as "www.site-name.com",
where site-name could be Yahoo, Ebay, or Amazon. The entire tail end
of the name "site-name.com" is also called a domain name. A domain
name is simply a unique address that specifies the location of a
website. Just like every physical location has a street address
(e.g. 123 Apple St.) which idenitifes its location (street number,
city, zip code), a domain name specifies the address of a website.
However, unlike your home address, web site domains are based on a
different structure that underneath it all, helps your internet
browser search through the entire world wide web to locate a
specific web page.
TCP/IP
In 1971 a protocol was developed called TCP/IP. Although it was not
fully adopted until 1984, TCP/IP became (and still is) the primary
method for computers to communicate over telecommunications
networks. The entire backbone of the internet is based on the TCP/IP
protocol. Without getting under the hood of TCP/IP and how it
operates, simply understand that TCP/IP is a communications language
that allows two computers (which may be different) to communicate
with one another. As part of this protocol, an addressing scheme had
to be developed so that one computer could identify another computer
over a network. This TCP/IP address or "IP Address" uniquely
identifies every location on the internet. A TCP/IP address is
composed of 4 numbers separated by a period. Each number can range
from 0 to 255. For example, an IP address may look something like :
123.45.67.89. Every network connected device in the entire internet
must be assigned a unique IP address so that communications can
occur between it and other computers.
Too Many Numbers!
Unfortunately, although the TCP/IP protocol provided for a simple
and effective way for computers to communicate across networks, it
did create problems as the size of the internet grew. If you can
imagine, in order for one computer to communicate with another, it
had to have knowledge of the IP address of the destination computer.
Certainly, you can see how hard it would be to maintain a list of
100 IP addresses and remember which destination computer is
associated with it. In order to make the process of remembering the
address of computers on the internet, a system was developed in 1984
called the Domain Name System. The domain name system established a
way to recognize host computers on the internet without having to
remember their numerical IP addresses. Using the domain name system,
a computer on the internet whose IP address is "54.123.44.11" could
call itself "www.amazon.com". Within the internet, there are domain
name servers which are computers that store the millions of internet
IP addresses and their associated domain name. So, when you type in
"www.amazon.com" in your browser, your computer first goes to one of
the many domain name servers on the internet, finds (or resolves)
the IP address associated with "www.amazon.com" and, using that IP
address, begins a communication session with the Amazon web site.
Get Them While They're Hot
Luckily, acquiring a domain name is very simple. In order to stake a
claim to a domain name to call your own, you must first find an
available name and then register the name with a registrar. A domain
name registrar is a company who is responsible for distributing
DOMAIN NAMES to people.
On our home page, you can register your domain name. DOMAIN NAMES
are registered yearly, if you let the registration lapse then
somebody else can register the name.
