Without a domain name, websites are specified by an IP address. What is an IP address? It is an identifier that is used by computers or humans to determine the location of a server or website. However, for humans, an IP address, (which is expressed in a numerical format), can be difficult to remember. This is why domain names were invented.

Why use a dedicated server? There are many reasons why you should choose to use a dedicated server. The most important reason is that you have full control of the server and no longer have to share space and bandwidth with other websites.
