The domain name system or domain name server (DNS) is a system that stores information associated with domain names in a distributed database of networks, such as the Internet. The domain name system (domain name server) associates many types of information with domain names, but most importantly, it translates the domain name (computer hostnames) to IP addresses. It also lists mail exchange servers accepting e-mail for each domain. In providing a worldwide keyword-based redirection service, DNS is an essential component of contemporary Internet use.
A domain name is a unique name corresponding to the numeric IP address of a computer on the Internet. Internet users access your website using your domain name. Domain name can be up to sixty-seven characters long.
A domain name registrar is a company accredited by the Internet Corporation for Assigned Names and Numbers (ICANN) to sell Internet domain names. ICANN has authority over gTLDs, or Generic Top Level Domains. Examples of gTLDs include .com, .net and .org. ICANN does not have authority over ccTLDs, or Country Code Top-Level Domains. Registrars compete with each other to provide the best support and services at the lowest price.
