the word domain itself has been widely spread on the internet. However, do you really understand what a domain is? In short, a domain is a website address. Enter the address that you entered into the URL bar of your preferred browser ending in .com, .c.us, .site, .ac.au is what is called a domain name.

Understanding Domain

What is a domain? Domain is the address that will take you to the website you are going to. Basically, a domain is a simple form of IP address which is a complex combination of numbers. With so many websites spread on the internet, memorizing these number combinations is certainly very difficult.

The domain function is a tool to identify a web hosting. An example domain, for example, is artsyken.com.

artsyken.com is the website you want to go to, while .co.id is the domain extension you choose. With a domain name, you don’t have to bother checking the IP address of the website you want to go to. Simple, right?

To have your own domain name, you need to register the domain name you want. The domain will be registered with an organization called ICANN (Internet Corporation for Assigned Names and Numbers) which determines which domain extensions can be used.

When registering a domain name, you can choose your website name and domain extension according to your wishes.

How Domains Work

After understanding what a domain is, it’s time to know how a domain works.

Still fresh in my mind that the domain serves as an address to take you to a certain website. You need to know, in this world there are millions of domains. Even though they are unique, it will still be difficult to find them if these addresses are scattered erratically.

Therefore, these domains are collected into a contact list. Think of it like a phone book. Now, this phonebook is called a DNS Server. It is your web hosting service manages this phonebook.

When the domain you are looking for is found on the DNS Server, the browser will display the page you want. However, if the address has not been found, it will be searched on another DNS server.

What are Domains and Subdomains?

Domains and subdomains cannot be separated. Subdomains can be used to separate other domains that are still children of the main domain you own. On Niagahoster, you can get a free subdomain if you have a domain registered here.

A subdomain is an alias for your domain. Usually, the subdomain will contain words or names that are more specific to your entire website. blog.domain.com is the subdomain of www.domain.com. The word “blog” in front of “domain.com” is what is called a subdomain.

Subdomains are usually used so that the content in them is not mixed with the main content of the user’s website. If you have an online store, but you also want to provide education about the items you market, you can create a “blog” subdomain. With this subdomain, you will not be confused about placing articles without destroying the aesthetics of your online store.

Not only is it useful to separate custom content from your main domain, subdomains have other benefits. The uses for subdomains include:

Search engines see subdomains as unique websites that are not linked to your main domain. This means that your subdomain rankings can also go up and gain ground on the main domain. Of course, this means you can shift down competitor websites.

If used correctly, they can also get indexed quickly and benefit from the primary domain.
Apart from subdomains, domains are also generally divided into three categories, namely Top Level Domains, Second Level Domains, and Third Level Domains.

TLD or Top Level Domain

In fact, a Top Level Domain is a domain extension that is behind the website name. TLD itself is a very popular extension. Among them, .com, .net, .gov, .org and others. Many prefer to use Top Level Domains for various reasons. One of them is because it is easier to remember and more common. This reason is usually used by websites that are more personal or do not refer to a particular organization. Top Level Domains also make hosting / client websites rank superior on Google search engines.

SLD or Second Level Domain

SLD is the domain name that you register. The way to read a domain is from the very back, then go to the front. Well, in the artsyken.com domain, the name “artsyken” is what is called SLD. More easily, you can interpret SLD as the name of your website.

Third Level Domain

Or what is often referred to as a subdomain. It is located at the very front of the entire domain name URL that you have. For example, “www.artsyken.com”, then “www” is categorized as a Third Level Domain.

Difference between TLD and gTLD Domain
There are two types of TLDs or domain extensions that are often used, namely gTLDs and ccTLDs. Most users don’t realize the difference, because they are both often found on websites that rank high on search engines such as Google.

gTLD or Generic Top Level Domain is a domain with a common extension and is the most widely used by users in the world. Domains that exist in this type end in .com, .net, .biz, .org, .edu, and others. Each extension also has its own description and usage.

  • .com: used for commercial purposes
  • .biz: used for business purposes
  • .org: used for organizational purposes
  • .edu: used for educational purposes

ccTLD – Country Code Top Level Domain means that the domain will carry the identity of the country and show that the content of the website is intended for people in that country, such as domains with the country initials ending .id, .sg, .au.

In Indonesia, there are many variations of domains that companies can use to complement their website URLs. Example:

.ac.id: used for academic / higher education environments with predetermined terms and policies.
.co.id: used for commercial organizations that are intended only for the company.
.sch.id: used for academics / schools
.web.id: used by Indonesian personnel and organizations.
