Domain registration is the process of acquiring a unique web address (domain name) through a domain registrar. This user-friendly name serves as the online identity for a website and is associated with a specific top-level domain (TLD) like .com or .org. The registration is typically done on an annual basis, involves a registration fee, and requires providing contact information. Domain owners can manage settings through a registrar's control panel. It's crucial to renew registrations to maintain ownership, and some registrars offer privacy services to protect personal information in the public WHOIS database.
