Final part of the domain name, that comes after a dot. TLD (Top Level Domain) refers to the Internet zone in which your domain name is located. It is also known as "extension".

There are several types of TLDs:

• generic, called gTLDs, such as .com .net .org .biz .info .name…
• national (one per country), called ccTLDs for "country code TLD", such as .fr for France, .be for Belgium…

For each TLD, a worldwide database guarantees that each domain name is the only one in the world. The organization that manages this database is called a registry. Each TLD is created and regulated by a trustee authority.

Changes in the database (creation, deletion, and/or modification of domain names) are made through registrars (such as Gandi), who are accredited by the trustee authorities and registries of the TLD.
