A domain name is the text a user types in a browser to reach a particular website. For example, the domain name of Epik is epik.com.
Domain names are used to identify, or label, a location on the web, that's defined by an IP Address. By using DNS, or the Domain Name System, domains allow for users to easily interface with and share content on the web.
Domain names are organized in subordinate levels (subdomains) which are prefixed to the DNS root domain, which is nameless. The first-level set of domain names is the top-level domains (TLDs) like .COM, and the different levels are separated by a dot.
