Domain name extensions are referred to as top-level domains (TLDs). A domain is the name of your website and is unique for every website, and you need to get your domain registered with a legal domain name provider. People use your domain name to find you over the internet as it is the address of your website. To make your website fully functional, you also need to purchase web hosting and register your unique domain name. Paul Mockapetris invented domain names to overcome the difficulty of remembering IP Addresses in numeric form. Domain names are in text, so they are easy to remember. A good domain name is short, easy to remember, and has a “.com” effect on its end. Domain’s history also helps keep the integrity of the domain name registration process since all registrations and ownership details are regulated and stored by ICANN (Internet Cooperation for Assigned Names and Numbers). This regulation restricts issuing and registration of the same domain name for more than one owner. In a nutshell, once you have decided to set up your website, you need to think of a short, concise, and descriptive domain name that reflects the purpose of your website in a straightforward way. Also, your domain name should be easy to remember so that your visitors don’t have to type a long URL to access your services. The first domain registered was in 1985.
