Explore the diverse world of internet domains and learn the easy steps to register your very own domain name in this comprehensive guide.

What is Domain?

A domain is a unique and easy-to-remember address that identifies a website on the internet. It serves as a human-friendly label for websites, allowing users to access them without having to remember complex numerical IP addresses.

For example, in the domain "," "mydomain" is the name chosen by the company, and ".com" indicates it is a commercial website. Domains are registered through accredited providers for a specific period, giving exclusive rights to the owner. By using domains, individuals, and businesses can establish their online presence and make their websites accessible to users worldwide.

How Domain Works

When you enter a domain name, your web browser sends a request to a special server called a Domain Name System (DNS) server. The DNS server acts like a phone book for the internet, translating the domain name into the corresponding IP address.

Once the DNS server finds the IP address associated with the domain, it sends it back to your web browser. With this information, your browser can connect to the server hosting the website you want to visit.

Types of Domain

Domains come in various types, each serving different purposes and suitable for various needs. Here's a comprehensive breakdown:

1. Top-Level Domains (TLDs)

TLDs are at the apex of the domain hierarchy. They are the suffixes found at the end of a domain name, such as .com, .net, .org, .edu, and .gov.

Generic Top-Level Domains (gTLDs): This is the most common type of TLD, including familiar extensions such as .com, .net, and .org.

Country Code Top-Level Domains (ccTLDs): These are country-specific TLDs that represent a particular geographical location. Examples include .us (United States), .uk (United Kingdom), .ca (Canada), and .au (Australia).

Sponsored Top-Level Domains (sTLDs): These are overseen by private organizations. Examples include .gov (US Government), .edu (Educational Institutions), .mil (US Military).

Infrastructure Top-Level Domain: This category includes just one TLD: .arpa, used for technical infrastructure purposes.

New Top-Level Domains (nTLDs): Introduced in 2014 by ICANN, nTLDs allow organizations to create brand-specific or niche TLDs. Examples include .google, .amazon, .apple, .bike, .photography, and more.

2. Second-Level Domains (SLDs)

An SLD is part of the domain name that appears directly to the left of the TLD and domain dot. For instance, in the domain name '', 'domainname' is the second-level domain.

3. Subdomains

A subdomain is a third-level domain that is part of a larger, primary domain. It's used to organize and navigate to different sections of your website. For example, in '', 'blog' is the subdomain.

4. Internationalized Domain Names (IDNs)

IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet. They enable internet users worldwide to navigate the web in their native languages.
