Domain name is case insensitive, which means Google.com,
google.com and gOOgLE.coM are the same. A dot act as a
separator in a domain name. The part after the last dot is
called the Top Level Domain (TLD). From the examples above,
their TLDs are:
Domain Name |
Top Level Domain (TLD) |
Google.com |
.com |
Php.net |
.net |
Linux.org |
.org |
Domain name registrations for the most seen .com, .net, .org are unrestricted
and are opened to anyone. They are usually referred to as International TLDs.
When the internet started a decade ago, it is recommended that companies should
use .com, internet service providers should use .net and organizations should
use .org. But today, these rules are no longer engaged and you can register
under any international TLDs you want.
Other international TLDs include .aero (for the air-transport industry), .biz
(for businesses), .coop (for cooperatives), .info (for all uses), .museum (for
museums), .name (for individuals), and .pro (for professions). But they are not
as popular as .com, .net and .org.
Choose a .com whenever possible! Most internet users are not familiar or even
aware of the other TLDs. They usually assume all domain names end up with .com.
Two letter domains, such as .uk (United Kingdom), .ws (Western Samoa) and .jp
(Japan) are referred as country code Top Level Domains (ccTLDs) and are
corresponded to a country, territory, or other geographic location. The rules
and policies for registering domain names under the ccTLDs vary significantly
and some are reserved only for the citizens of the corresponding country.
You might notice that for the some ccTLDs such as .uk or .my (Malaysia), the
domain name has an extra portion between the name and the ccTLDs. For example
chosenname.co.uk or chosenname.net.my. These arrangements are also depends on
the rue corresponding country.
Some small countries such as Western Samoa (.ws), Tuvalu (.tv) and Belize (.bz)
have chosen to offer domain registration of their ccTLD to the public to raise
funds for their countries.
When you register a domain name, you do not need to register the 'www'. When you
own a domain name, you can add whatever you want to the front with a dot as
separator, such as www.yoursite.com, ftp.yoursite.com, daddy.yoursite.com,
mydog.yoursite.com, etc. They are called sub domains.
Every different subdomain can be configured to serve different purposes or as
different websites. Following the tradition, the subdomain www.yoursite.com will
be used as your main website address which is actually an alias to yoursite.com.
That means your visitors will see the same website no matter they visit
www.yoursite.com or yoursite.com. Nowadays, people use sub domains as the
addresses for other websites, such as setting up dog.yoursite.com as a website
for your dog!
Why do you need a Domain Name?
All domain name must be unique and once your registered it, you OWN it until the
expiry date. The minimum registration period is 1 year but you can choose to
renew it up to a maximum of 10 years.
You can do whatever you want with the domain name. You can setup a website,
setup an email account, or do nothing with it! With all the rights to your
domain name, you can decide where to host your site and you can change your host
anytime you want, without depending your fortune to any specific host.
Let me tell you a real story. Virtualave.com is once a free web hosts. Many
people lauched their first website with them and had their site address as
something.virtualave.net, which is a sub domain address. They DO NOT own the
address but Virtualave. And what happened now is Virtualave no longer offer free
hosting and if you want to keep your address, you need to pay at least
$10/month!
Another story is even more scary. Xoom.com is also once a popular free web
hosts, actually one of the best. It will be a nightmare for people who have
established a site with a XOOM address that look like members.xoom.com/mywebsite
(a subdirectory address). WHY? because they are out of business and the address
is no longer available even if you are willing to pay $1,000/month for it! For
all the time, you are promoting your website with someone else addresses. You
make all the references to your website with somebody else domain name. And now
imagine if you have 1,000 visitors hitting the old address everyday? You LOST
1,000 visitors just because you didn't choose to promote your site with your own
domain name at the very first place!
A domain name will also make you look BIG and professional. Let's say you are a
web designer. Do you think your customers will be more interested to take the
services from michaelwebdesign.com or davidwebdesign.netfirms.com? Netfirms is
currently the most popular free web host, but who can guarantee if they will not
end up like Virtualave or Xoom, which were also once POPULAR?
The reasoning above also show you why you shouldn't host your site with a free
web host. If you want a free web host, you must look for some that will host
your own domain name. Protect yourself and don't bet your live with other's
fortune. And keep in your mind, nothing is really FREE and someone will have to
pay the bills.
How do you register a domain name?
You register your domain name with a domain registrar.
And there are really a lot of domain registrars available and prices do vary
among registrars even for registering the same domain name! That's why if you
know where to register for cheaper domain names, you can save a few dollars. I
am happy that you have read until here because I will tell you that!
Currently, you can register a domain name for as low as 100 LE at Microlife! All
you need to do is to check your domain availability and pay for it. That's all.
Microlife currently offer registration for .com, .net, .org, .biz, .info and .us
only.
DNS (Domain Name System) Servers
Each domain name must be associated with 2 or more DNS
servers. The DNS information act as a bridge between your
domain name and your host. That means in order for the
internet to know who is your web host, they will need to
look at the DNS info associated with your domain name.
That's why your web host cannot keep you hostage because you
can simply change the DNS info and your domain name will be
pointed to your new web host!
Each web host will setup their own DNS servers. They look
something like ns1.yourhost.com and ns2.yourhost.com. All
you need to do is to enter the 2 DNS servers given by your
web host to your domain name. Your domain registrar will
have a place where you can fill up these information. It is
a simple and straightforward task. If you register your
domain name through your web host, they will enter the DNS
information for you.
Because the internet is so large, after you register a new
domain name or update the DNS setting, it usually takes 1-3
days for the entire internet to notice the new DNS setting.
This process is called DNS propagation. That's why new web
hosting customers will not be able to see their website
immediately after they setup their hosting account. It is
normal and don't blame your web host on this! Your website
will appear after the DNS propagation is completed.
