What is an Internet domain name registry?
For the Internet to function and to prevent duplication of web addresses there has to be one authoritative place to register a domain name. Each TLD has an authoritative registry, which manages a centralized database. The registry inputs the information about domain names in TLD zone files to enable communication over the Internet for applications like credit card processing, bank transactions as well as Web browsing and email. A registry provides direct service to registrars who provide direct service to domain name registrants.
