What is a Domain?

A domain is a unique name that identifies a website or computer connected to the Internet. It is essentially a set of characters (alphanumeric and/or hyphens) that define a web address. The domain name is used to easily find and access a website, or other resources available on the Internet.

Types of Domains

There are several types of domains, each with its own purpose:

  • Top Level Domains (TLDs) – These are the most common types of domains, and include .com, .org, .net, and many more.
  • Country Code Top Level Domains (ccTLDs) – These are two letter country codes assigned to each country, such as .uk for the United Kingdom and .de for Germany.
  • Second Level Domains (SLDs) – These are domains that are registered under a TLD, such as or
  • Subdomains – These are domains that are created under an existing domain, such as or

Domain Registration

Domain registration is the process of purchasing a domain name for a website. Once a domain is registered, it is then associated with an IP address, which is a numerical representation of the domain name. After registration, the domain name is then eligible to be used for a website, email address, or other online services.
