What does the term domain registrar mean?

A domain registrar is an organization or company that manages the reservation of internet domain names. They are accredited by the Internet Corporation for Assigned Names and Numbers (ICANN) or national authorities to sell and manage domain names on behalf of customers. When individuals or businesses want to secure a domain name, they register it through a registrar, which handles the necessary technical details and maintains the domain's registration. Additionally, registrars often provide services like domain transfer, renewal, and DNS management.
