What Is a Domain? (And How to Buy One?)

Think of a shop without a label; people can’t easily find it, right? Even if they find it, it will be difficult to remember. A domain name is precisely the label of websites. It is the name and exact address of a site.In this article, we will talk about what is it, where to get one, what are the extensions and, what are they used for.

What Is a Domain?

Names like www.amazon.com, www.google.com, www.facebook.com are domain names. All of the content (HTML, CSS, JavaScript, PHP files, photos, and videos, etc.) that make up the website are kept on the servers. For the website to work, the I.P. address of the server must be accessed in the directory. I.P. addresses are the identification numbers that enable computers to communicate with each other over the network. Websites are also stored in computers that are always connected to the internet, without power cuts, and running fast. These computers are called “servers.” For the websites to work, it is necessary to connect to this server with an I.P. address. However, keeping in mind and accessing an I.P. address like will not be easy. This is precisely where the domain comes into play.

Thanks to DNS servers, it connects to I.P. addresses and enables the site to open. Instead of keeping complex number series such as in our mind, we keep a name like www.reddit.com. When we write this name in the address line of our browser and make a request, our domain name is directed to the relevant server and brings the site. 

What Is a Domain Name and Top Level Domain?

The “amazon” part of the www.amazon.com is the name, and, the “com” part of the www.amazon.com is the Top-Level Domain (TLD). TLDs are the top-levels of domain names. TLDs such as com, net, org, and info, which differ at the end of each name, are among the most used. Which of these to choose is related to the style of the site. Because every TLD means something. However, nowadays, it is difficult to find a free name, and in some cases, the empty one is purchased without paying much attention to the upper levels.

Let’s get to know TLDs. First of all, these domains are divided into two in every country. TLDs used internationally, and TLDs used geographically.

international domain

International Top-Level Domains

These are taken from companies registered in the ICAAN consortium from the USA. In such domains, the first applicant receipt rule is validated. This means, for instance, you set up a company, you named it black pineapple, and you think the most suitable name for you is www.blackpineapple.com. However, you can only buy this if someone has not purchased it before you. If someone has purchased and is not using it, you can contact the purchaser in some way and ask them for it. However, here you have to reach an agreement with how much money the owner wants.

This situation caused domain-hunters to derive and even become a sector. The most commonly used domains such as com, net, org were collected with high word names, and most of them were parked idle but waiting for their buyers with high fees.

geographical domain

Geographical Top-Level Domains

These TLD types have the same extensions as international ones; the difference is that the country code of the country in which they are registered is added to the end. For the U.K., this code is “.uk”. In other words, it is the domain co.uk, the geographical location for the com used internationally. The most common ones are again co.uk, net.uk, org.uk, gov.uk, edu.uk. In the example of “Black pineapple” we provided, the domain name www.blackpineapple.com can be purchased by the first applicant, but it can be bought as www.blackpineapple.com.uk. from Nominet U.K. with some requirements. It is the responsible company for .uk domains.

However, domain purchases are made through intermediary companies.

Whois information

What is Domain WHOIS Information?

WHOIS (Domain Name Search) contains the information of the person and/or organization to which the domain or I.P. number belongs.

WHOIS information includes various information about the registration and termination dates of the, and who the name owner is. Under ICANN rules, name owners have to enter whois information completely. Registrars give the right to the domain registrants to edit this information from the administration panel.

    Great post! You did a great job explaining what a domain name is and how it works. One suggestion I have is to add more examples of domain names to help readers better understand the concept.
