Domain registrars allow businesses and individuals to reserve and register internet domain names. These platforms are used by organizations that wish to create and maintain a website, protect their brand, or reserve a domain name for future business opportunities.
When a domain is registered, it is reserved for a set period, typically one year by default, but often extendable up to ten years, after which it must be renewed to maintain ownership. Registrars also offer services such as domain availability searches, transfers between providers, and domain parking, where the name points to a placeholder page or simple advertisement until a full site is developed.
To operate legitimately, registrars must be accredited by governing authorities. For most generic domains (like .com or .org), this accreditation comes from the Internet Corporation for Assigned Names and Numbers (ICANN). For country-specific domains, regional bodies oversee the process, for example, Nominet for .uk.
Many registrars go beyond registration by offering managed domain name system (DNS) solutions, which handle the translation of domain names into IP addresses and ensure traffic is routed reliably. Many of these platforms also provide DNS security features such as domain name system security extensions (DNSSEC) or protection against spoofing, though more advanced defenses like distributed denial of service (DDoS) mitigation may be available only through specialized providers.
Together, domain registration, DNS management, and security measures create a unified system that allows organizations to establish, control, and protect their online presence.
To qualify for inclusion in the Domain Registrars category, a product must:
- Offer a searchable domain registry to check domain name availability
- Process domain name registrations and renewals for customers, ensuring continued ownership of purchased domains
- Support domain transfers both in and out, enabling customers to move domain names between registrars in compliance with ICANN policies
- Maintain active accreditation with the appropriate domain registry authorities, such as ICANN for generic top-level domains or regional/national registries for country-code domains
