What is the difference from Registry and Registrar?

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.

Registrars and new gTLDs Stats

There are 40.520.400 domains registred around the world, 1115 TLDs, and 458 Registrars. You can see all stats on ntldstats.

The market covered by each registrar varies a lot. The stats I'll show is the domains bought on different registrars.

See the chart below:

At the top we have Godaddy with 6,378,961 domains (15,74%), followed by Namecheap with 5,673,915 domains (14%), and then all the others that don't reach 10%.
