Do you know , What is a domain?

Published: Feb 16, 2012

A domain name is a Web address, such as chennaihost.com, that is linked to an IP address (which represents a physical point on the Internet). When someone types a domain name into a Web browser, the requested Web page displays.

A domain name consists of a top-level and a second-level domain. A top-level domain (TLD) is the part of the domain name located to the right of the dot (chennaihost.com). The most common top-level domains are .COM, .NET, and .ORG. Some other popular top-level domains are .BIZ, .INFO, .NAME and .WS. These TLDs have certain guidelines but are, for the most part, available to any registrant, anywhere in the world.

chennaihostThe part of the domain name located to the left of the dot “chennaihost” in this case is called the second-level domain (SLD) name. The second-level domain name is the “readable” part of the address and refers to the organization or entity behind the Internet address. Second-level domain names must be registered with an Internet Corporation for Assigned Names and Numbers (ICANN)-accredited registrar.

Every domain name has a suffix that indicates which top level domain (TLD) it belongs to. There are only a limited number of such domains. For example:

  • gov – Government agencies
  • edu – Educational institutions
  • org – Organizations (nonprofit)
  • mil – Military
  • com – commercial business
  • net – Network organizations
  • ca – Canada
  • th – Thailand

Because the Internet is based on IP addresses, not domain names, everyWeb server requires a Domain Name System (DNS) server to translate domain names into IP addresses.

Difference between Addon Domain, Sub Domain and Parked Domain

You might have heard of Addon Domain, Sub Domain and Parked Domain while you approached your web host for hosting your website. These domains are very important and they should be know by a webmaster-

Addon Domain

An add-on domain is just like having a separate web site. The add-on domain will be hosted or pointed to a folder in your public_html folder of your main-domain. The Add-on domain should be already registered and the nameservers for the add-on domain should be pointing the same nameserves as your main-domain.com.

[ consider your addon domain name as addondomain.com ]

There are 3 ways of accessing an addon domain:

1. addondomain.com

2. main-domain.com/addondomain

3. addondomain.main-domain.com

Accessing the addondomain.com will display that very domain name in the address bar of their browser, so its similar to a separate web site. An add-on domain use the space and bandwidth available to the main domain. An add-on domain will have its own CGI and FTP access, its own email accounts and web stats.

Sub Domain

A sub domain utilises the existing main domain name. It does not have its own domain name. A sub domain points to a folder in your public_html directory of your main-domain. Consider you main domain ” main-domain.com” and you have a folder “shop”  under your public_html directory. You can create a sub domain “shop.main-domain.com “. You can directly reach the shop page by accessing “shop.main-domain.com”. You might have seen “mail.yahoo.com”, ” mail.google.com”. These are sub domains for yahoo.com and google.com. Check out our sub domain for Techcuriosity forum ” forum.techcuriosity.com”.

Parked Domain

A parked domain is one which simply points to an existing domain. It is an other domain which is parked on to the main domain. Consider a domain ” parked.com”  which is parked on the “main-domain.com”. If we access parked.com it will be directed to the main-domain.com and you will get the same page as you see while accessing main-domain.com. The parked domain should also point to the same nameservers as the main-domain.com. The park domain name should be registered.
