A domain name is a sort of label of identification that provides a user with control in the internet environment, authority, and administrative autonomy. A domain name can also be referred to as a hostname that recognizes IP addresses. The Doman Name System (DNS) forms domain names by procedures and rules. Domain names are organized in subdomains (subordinate levels) of the DNS root domain and are used in numerous addressing and naming application specific purposes and a host of networking contexts.
Top Level Domains, also known as TLDS, are the first level set of domain names which includes the generic TLDs such as org, net and com. There are also ccTLDs, known as country code top level domains. The next level of domain names are what is called the second level and third level domain names which are usually open to end users that desire local area networks to be connected with the internet, develop additional accessible internet resources for the public, and run web sites. The domain name registrars are the ones that usually are responsible for registering domain names. The domain name registrars also sell services they have to the public. Domain names are used as hostnames or host identifiers by individual internet host computers.
Domain names are sometimes used as a means of simple identification in which to point out control or ownership of a resource. Examples of this would be identifiers in DomainKeys which are used to confirm DNS domains within systems of email, the Session Initiation, and in numerous other Uniform Resource Identifiers. One of the most significant purposes of domain names is to supply names that can be remembered easily and are very recognizable to numbered internet addresses.
