Domain Name Search and Availability: Registrars offer tools to search for available domain names with various extensions (.com, .org, .net, .in, etc.) and help users find a suitable name for their website.

Registration and Renewal: Once a domain name is chosen, it needs to be registered with a registrar, and the registration is typically valid for a set period (e.g., one year). Renewal ensures continued ownership of the domain name.

Domain Privacy Protection: Many registrars offer privacy services to protect the registrant's contact information from being publicly available in the WHOIS database.

DNS Management: Registrars provide tools for managing the Domain Name System (DNS) settings of the registered domain, which are crucial for connecting the domain name to the website's hosting server.

Domain Transfers: Registrars allow users to transfer their domain names from one registrar to another.
