Definition — What is a Domain Name?


A Domain name is the web address that people type into the URL browser box to access your website. In the simplest of definitions, a domain name is your website’s address on the internet. Each computer is assigned a unique IP address, which is a series of numbers. This IP address allows other computers to communicate with one another. However, it is difficult for humans to remember strings of numbers. Domain names were developed to solve the problem of difficult to remember IP addresses. A domain name can be any combination of letters and numbers, and it can be used in combination with the various domain name extensions, such as .com, .net, and more.

Some examples of domain names include:

Manageengine.com

Servicedeskplus.com

Zoho.com

 

A domain name is the permanent address of your website on the Internet. It functions on the Internet in a manner similar to a physical address in the physical world. Every domain name is unique. No two websites can have the same domain name. Domain name registrations are overseen by an organization called ICANN (Internet Corporation for Assigned Names and Numbers). ICANN specifies which domain name extensions are available and keeps a centralized database of where the domain names point to. When visitors enter your domain name in their browsers, their computer sends a request to a cluster of servers called the DNS (Domain Name System) in turn DNS responds with the IP address of your website’s hosting server, which is how people are able to use your domain name to reach your website. Every website consists of two main elements: a domain name and a web server. A web server is a physical machine that hosts the files and the databases that your website is made from and sends them out to people across the internet when they visit your site from their machine.

 

Different Types of Domain Names

  • Top-Level Domain – TLD: refers to the suffix or the last part of a domain name. Examples : .com, .gov, .edu, .mil, .net, .org

  • Country Code Top Level Domain – ccTLD: Two-letter domains established for geographical locations. Examples : .in, .au, .uk
  • Generic top-level domain - gTLD: The gTLD category contains all the most recognizable TLDs. Examples : .info, .gov, .biz
  • Second-Level Domains: Within the DNS hierarchy, second-level domains are domains that follow TLD.
  • Third Level Domains: Third level domains are below second-level domains in the domain name hierarchy.
