Domain (domain name) is a naming technique developed by the internet authorities to replace hard-to-remember IP addresses. That is, the name that you choose for your site, which is used with the extension, for example .com, .net. This is called a domain name or domain. If you have a website, then the domain is like the address of your home. One of the most accurate definitions of a domain is “your site’s name and address,” because users access your site using your domain name.
