What Is a Domain [Different Types, Choosing & Buying One]


The language of the internet can often be confusing. For example, some of the terms we often encounter when discussing websites are ‘domain’ and ‘domain name,’ which are often used interchangeably. This article addresses what a domain is, how it works, and how you can choose and acquire one.

What Is a Domain?

A domain is a group of users, computers, or servers that share various data via a network and have the power to assign certain privileges. In a network domain, many computers (or other devices) can be directly connected. Additionally, numerous servers can exist in the same domain.

What Is a Domain for a Website?

In the simplest terms, a domain is the name of the website. When you acquire a domain, you obtain the site’s name, even though the site itself might not yet be operational. Each website available on the internet has its own IP address—a string of numbers unique to each site and connecting computers to web servers.

IP addresses, however, are long, complicated strings of numbers, difficult to remember, which is where the domain comes into play. The domain transforms the IP address into a web address using a Domain Name System (DNS) server. The result is used to identify websites and give people the opportunity to remember the site easily.

What Is a Domain Name and How Does It Work?

The terms domain and domain name are used to refer to the same thing when discussing websites. The domain name identifies a network or IP resources, such as a personal computer used to access the site. This server computer that acts as a host for the site, or any other action occurring on the internet.

Each domain name is one of a kind—there are no two identical domain names on the internet. So, when someone types a specific domain name into their browser, it directs them to only one website that corresponds to that unique name.

What Is a Domain Controller?

A domain controller is a server that responds to authentication requests on a network domain. The controller verifies users on the networks, stores information, and keeps all data organized and secure.

What Are Domain Names in a More Technical Sense?

Domain names include a string of characters (letters or words). Each domain consists of two parts: top level domain (TLD) and second-level domain (SLD). The second-level domain is located before .com and distinguishes your site from all others on the internet.

Domain names consist of 63 characters. (This should be kept in mind when choosing a name for your website.) The names shouldn’t include any spaces or symbols, except hyphens. It’s also best to avoid using numbers in the name of your site.

What Is a Top Level Domain?

A top level domain (or extension) is the part of the name that follows the second-level domain and specifies your business’s entity type on the internet—for example, .com, .org., .net, or .gov. There are more than 1500 top-level domains available for use on the internet.

Why Is a Domain Name Important?

Domain names are essential. They allow your site to be easily discoverable on the internet and prevent it from being lost among the millions of other sites located in a vast cyberspace. The public domain definition includes anything available on the internet. (You want your site to be accessible to anyone, anywhere.) Additionally, a good domain name can help you establish the credibility of your website and create a brand for whatever you’re selling or promoting.

Types of Domain Names

Each domain is followed by a suffix, indicating which top level domain (TLD) the website belongs to. The number of these domains is limited. Some of the most common domains currently in use include:

  • .gov – government agencies
  • .edu –  educational institutions
  • .org – organizations (usually nonprofits)
  • .mil – military
  • .com – commercial business
  • .net – network organizations

Based on these examples, you may ask, ‘what is a domain in a website,’ and why is it so important? First, the domain distinguishes the site from everything else on the internet—it’s the site’s fingerprint.

The domains listed above are known as generic top-level domains (GTLDs) that were created to be used by networks, organizations, and companies. But their use is unrestricted; anyone can acquire one of these domains, even for a personal site. Since the internet establishment, more than 1200 TLDs have been added to the original generic set and are now available for commercial use.

What Is a Website Domain That’s Country-Specific?

A country code top level domain (ccTLD)  is a two-letter domain that distinguishes various countries on the internet, for example, .us (US), .ca (Canada), .uk (UK), .au (Australia)—although these are not as frequently used as other, more popular domains. Their use is restricted to people and organizations based in the country the domain belongs to.

What’s a Domain Classified as a Sponsored Domain?

A sponsored top level domain (sTLD) is a specialized domain representing the community served by the domain. The communities served by sponsored domains are formed based on a geographical, ethnic, or professional basis. These domains are established by a sponsor that serves as a representative for the community in question.  Examples include .aero, .asia, .gov, .mil, .edu, and numerous others.

Buying a Domain Name

Anyone can obtain a domain name. The process of acquiring a domain is often referred to as ‘buying a domain,’ but the process is more similar to renting. When you acquire a domain and register it in your name and site, you have the right to use it during the rental period. Typically, domains are leased for at least one year. If you don’t renew your domain after this period expires, you can lose your right to it.

The domain name definition requires your name (or name of the business) to be listed on the domain registration. If you register your domain through a third party, they should list their name on the registration. In this case, the third party owns the domain rights and can manage it however they wish.

Your domain could even be sold to someone else, which is why you need to be careful to list your name and ensure that you’re the one paying the registration fees, so you’ll be able to retain all rights to the domain. The buying process, itself, is simple—find an online domain name registrar, type in your chosen domain name, and choose the payment method.

What Is a Domain Registrar?

A domain name registrar is a company that has received accreditation from the Internet Corporation for Assigned Names and Numbers (ICANN) to sell and register domain names, as well as assign IP addresses for those names. All domain names are entered into a domain registry overseen by ICANN, which manages all domain names.

What Is a Web Domain Registrar Concerning How It Works?

Domain registrars are repositories of domain names that they sell to clients, either directly or through resellers. It’s always better to get a domain name directly from the registrar if you wish to receive good service. If there are changes to the domain name, the registrar will notify the registry then update the database name. Once you’ve acquired the name and you’ve had it officially registered, you can do whatever you like with it:

  • Create a website, a blog, a personal email address.
  • Sell it.
  • Keep it idle (known as ‘parking’).

There are various accredited registers you can choose from that offer different prices. For example, the price for a .com ranges from $10.00 to $18.00. But prices can vary, depending on the registrar, extension, and type of domain name.

Tips for Choosing the Best Domain Name for Your Website

When choosing a domain, be careful to make the right choice since the domain name is a crucial part of the future success of your website. The website domain definition allows you to choose any extension you like for your site. Still, it’s advisable that you choose a more recognizable one, such as .com, so people can quickly locate your site.

What Is a Domain Besides the .com?

This part of the domain might prove to be a bit complicated since what comes before the .com needs to be unique. The number of sites on the internet (especially in the .com sector) makes it challenging to find a name that hasn’t already been taken.

It’s also essential that the name you choose for your domain matches the name of your business (or is similar to it) and is related to the central theme and content of the site. Don’t make it any longer than it needs to be. And try to fit a keyword in the domain, which will help increase the site’s ranking.

So, What Are Domains, and How Do You Create a Good One?

Domains are merely names, which should be simple, so anyone can spell them and pronounce them with ease. It’s best if you stay clear of double letters, numbers, and hyphens. If you’re buying a domain name for your site or blog, you can use your name as the domain—this will likely be available unless someone with the same name has already registered the domain.
