What is Domain and Subdomain? Why should I Buy Domain Name?

Why Domain Name Meaning of Domain Name, how domain works, Domain Name Structure, what is sub-domain and why should you register Domain Name?

Purchasing a domain name is the very first step to have an internet presence for an Individual, business or organisation. To make your identity online i.e. creating a website or blog, you need to buy a domain name.

What is Domain Name?

In simple words, a domain name would be the address of your site or blog. Domain name always ends with an extension of two or more characters like .in, .com, .info etc. We commonly called it as a website address. Internet users will find or identify your website through your unique domain name. To understand better just have a look on these examples of Domain Name.

i) google.com
ii) aubsp.com
iii) superwebtricks.com

Actually, domain name was developed so that people can easily remember alphabetical characters, I mean name, word or letters used for Internet Protocol (IP) Address. IP address is a series of number to identify devices on the internet. Did you know? Each and every device that connect to internet is issued with a unique IP Address. In other words, same IP address cannot be used simultaneously by two or more devices viz. Personal Computers, Laptops, Mobile phones or web servers.

The domain name Google.com is used for IP address and accordingly you can now understand the reason behind domain name used instead of IP address. That means it is far easier to remember SuperWebTricks.com instead of long set of numbers i.e. IP address of my site Showeblogin.

How Domain works?

Domain name works through DNS (Domain Name System) which is also known as DNS server, or name server. Whenever we type a domain name in any internet browser, a DNS service immediately translates that domain name into the corresponding IP address.

For example, the domain name SuperWebTricks.com identifies my Showeblogin website. When a user types the domain name SuperWebTricks.com in their web browser, the DNS server will translate the domain name into IP numbers which shall be used by the Internet to connect the user to my site SuperWebTricks.com

Domain Name Structure

There are generally four parts in a domain name viz. Prefix, Subdomain, Name and Extension. For better understanding have a look on my site address http://www.superwebtricks.com

a) Prefix:

The Prefix part of a domain name is an internet application protocol of the domain.

Standard Prefix: http://
Secured Prefix: https://

b) Subdomain:

Sub-domain is a third level domain of website name. Subdomain has been discussed separately. In my site domain “www” is subdomain. However, some website owners do not use www part i.e. the web address would be http://superwebtricks.com

c) Name:

The second level domain of the website is the main Name of your website address, picked by the person registering the domain.

d) Extension:

The top level domain can be picked for the variety of available choices.

Therefore, domain name is a combination of Name and Extension i.e. superwebtricks.com

What is Sub-domain?

Sub-domain is a part of main domain name. By default, www is a subdomain of the main domain. You may create a subdomain to separate different areas of your site instead by buying another domain name. Such subdomain can be used for defining unique content areas of your website. Thus, you may also say that subdomain is a second website, with its own unique content, but there is no new domain name. I have created a subdomain for pictures on my site. For example, in the domain name img.superwebtricks.com, “img” is a subdomain of main domain superwebtricks.com

Suppose you want to create a discussion forum or blog for your site then you may create forum.yourdomain.com or blog.yourdomain.com as the case may be for community/forum or blog for your site. Subdivision can go down to 127 levels deep and each DNS label can contain up to 63 characters. However, the whole domain name does not exceed a total length of 255 characters.

Actually, img.superwebtricks.com is subdomain of superwebtricks.com domain, which in term is a subdomain of the com top-level domain (TLD). A top-level domain is a domain name in the Domain Name System that is a direct subdomain of the DNS root zone.

Why do I need a Domain Name?
