What is a registry?
A registry refers to an organization or entity responsible for managing the database of domain names within a particular top-level domain (TLD). This includes maintaining the technical infrastructure and ensuring the smooth operation of the domain. They create domain name extensions, set the rules for that domain name, and work with registrars to sell domain names to the public. Functions of a Domain Registry:
Database Management: Keeping a record of all registered domain names under the TLD, including their associated information.
Technical Operations: Ensuring the availability and stability of the TLD's DNS (Domain Name System) infrastructure.
Policy Implementation: Enforcing the policies and rules for domain registration, set by ICANN (Internet Corporation for Assigned Names and Numbers) or other governing bodies.
Security: Implementing measures to protect the domain name system from abuse, such as cyber attacks.
Examples of Domain Registries:
Verisign: Manages the .com and .net TLDs.
Public Interest Registry (PIR): Manages the .org TLD.
Afilias: Manages various TLDs including .info and .mobi.
