“TLD” (Top Level Domain) refers to the final part of the domain name that comes after the dot. It represents the Internet zone in which your domain name is located. It is also known as an “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.
