4. Different types of domain extensions
Top Level Domains (TLD)
Country Code Top Level Domains (cCTLD)
Generic Top Level Domain (gTLD)
4.1. Top Level Domains (TLD)
As you know already that domain extension is a part of the domain name and it comes with
many types. Top level domains (TLD) covers all type of dormain extensions other than
country based domain extensions. For instance the domain extensions like .com, .org,.net,
edu will come under top level domains and the country based domain extensions like
co.uk, .in, will not come under the top level domains category. So in simple words, top level
domain extensions covers all the domain extensions except the country base domain
extensions.
4.2. Country Code Top Level Domains (ccTLD)
All the domain extension which are represented by a country is called as country code top
level domain extensions. There is a specific domain extension to represent each and every
country. For example, co.uk is for United Kingdom, .in for India, .com.au for Australia and
similarly there are unique domain extension representing each country. All these country
based domain extensions will come under country code top level domains (ccTLD)
4.3. Generic Top Level Domain (gTLD)
Generic top level domain is one of the type within the top level domain. There are over
1500+ top level domains at the moment and some of the most commonly used generic top
level domain extensions are .com, .org, .net,.info, .pro, .biz, and many more. However the
registrations of certain generic top level domains needs some proof of legibility. Generic top
level domains are maintained by the Internet Assigned Numbers Authority (1ANA) for use in
Domain Name System of the Internet.
5. Domain Structure
A normal domain name is composed of three sections like top level domain, second level
domain and third level domain.
URL (Uniform Resource Locator) of a website is usually contains three main sections like top
level domain, second level domain and the third level domain. For example, here lets take
www.clickdo.co.uk& classify the parts.
5.1. TLD (Top Level Domain)
In www.clickdo.co.uk top level domain is the .co.uk which is a country code top level
domain extension. So in this URL.co.uk is the cCTLD
5.2. Second Level Domain
In www.clickdo.co.uk second level domain is the one which is found left of the cCTLD or TLD.
That is "clickdo" which is found left to the dot of the TLD is the second level domain. Clickdo
is the second level domain in the URL www.clickdo.co.uk
5.3. Third Level Domain
Third level domain is optional and in most cases it is more customizable. Based on the
requirement, you can create your own third level domain name. For example, lets take an
example of UK Business Blog- https://business.clickdo.co.uk. In this .co.uk is the ceTLD,
clickdo is the second level domain, business is the third level domain. So the third level
domain can be customized as per the requirement.
6. Who owns a domain name?
The person who registers the particular domain name with the registrar owns that particular
domain. So the domain owner who registers has the full control of that domain. The domain
once registered will not be available for buying for others. For instance, we have already
registered a domain called clickdo.co.uk and hence this domain will not be available for
registration unless the domain owner of the clickdo.co.uk drops this domain or fails to
renew.
6.1. When to renew a domain name?
By default, when you register a new domain. It comes with 1 year renewal period. After that
the particular domain will expire. Hence you need to renew the domain name every year to
own it. If you fail to renew the domain, then that particular domain will be available for all
and anyone can buy it using any domain name registrar like SeekaHost. So if you register
any new domain, you should always renew on time.
What happens if you fail to renew tour domain name?
6.2.
So if you fail to renew your domain in time, then that particular domain will expire and you
will not have any control/access over it. Before moving forward, you need to know about
the some of the terminologies which are listed below.
.Domain Name System (DNS)
Domain Name Registry
Domain Registrar
Domain Reseller
Domain Registrant
Domain Name System (DNS)
6.2.1.
DNS Domain Name System is the decentralized naming system for the computers and the
other resources connected to the internet. ldeally, domain name system will map the IP
addresses to the easily remember-able domain names in the internet.
As you know that human's use domain names to access the website. But the computers
uses series of numbers called IP addressed to access the website. So when the user types in
and searches for any domain name in the web browser. DNS finds the appropriate IP
address of the domain name which is typed by the users and loads that particular website in
